The Theory Of The Equilibrium System

Procedure: In this experiment, various chemicals were mixed together, to determine a reaction. Using two drops from chemical 1 and two drops of chemical two, unless otherwise stated, then recording the type of physical reaction or color changes that occurred.

The main objective of this experiment is to differentiate between a physical change and a chemical change.

Background Information: We are going to use our knowledge of the Le Chatelier’s principle in order to observe this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects of the change.

The objective of the experiment is to apply Le Chatelier's Principle, which is a system that responds to an external stress and then adjusts itself in order to alleviate the stress when it is at equilibrium. A reactant is added, and the equilibrium is reestablished, resulting in more products and fewer reactants, and thus, the position of equilibrium is shifted to the right. When a product is added, the equilibrium position is shifted to the left because there are more reactants and fewer products.

The objective of this experiment will be to combine various substances, liquids and metals, and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical.

Regarding temperature, Le Chatelier’s principle states that seeing as the production of COCl2 from CO + Cl2 comes about through a process of exothermic reaction, that the reverse would come about through a process of endothermic reaction. Therefore increasing the temperature would cause a reduction in the equilibrium yield of COCL2 favouring the original reactants CO + Cl2. (163)

The objective of the experiment was to observe different reactions with different chemicals. The experiments emphasized on the chemical changes occurring in acids and bases as well as color changes and bubble formations. The experiments allowed for a better understanding of the undergoing chemical changes in mixtures. Some mixtures instantly changed colors while others were transparent or foggy. Some mixtures produced thick color that created solids called precipitates. Mixtures KI + Pb(NO3)2 and NaOH + AgNO3 both produce noticeable precipitates after a while. It was interesting to see the different acidic and base reactions like the fuchsia color formation in NaOH + phenolphthalein.

This shows Le Chatelier’s principle as the system was able to neutralize the disturbance from its equilibrium.In this case, the change was the addition of molecules to the reactants. This caused an increase in the number effective collisions between the reactant’s molecules. Also, this raised the rate of the forward reaction. The system then has an increased amount of reactants and therefore has to travel in the forward direction to make extra products. This occurred in order to return the system to equilibrium by removing some of the excess reactants. By shifting in the forward direction, more products are being produced by the excess reactants. This ensures that the forward and reverse reaction rates are equal, which brings the system back to a state of

Principle states that if a changed is placed on a system at equilibrium, the position of equilibrium will shift in the opposite direction. It will shift in a direction to reduce the change. Concentration, temperature, and pressure all affect equilibrium. When concentration is is changed, the equilibrium constant, k, will not change, however the equilibrium position will shift. For example, if a component (reactant or product) is added to a reaction system at equilibrium,

All proprieties of matter contain molecules that are either solids, liquids, or gases and carry factors of kinetic energy to do work. These molecules move at a random but constant speed from areas of high concentration to low concentration in a solvent through a semi-permeable membrane. This is called diffusion, and when cells diffuse water through a membrane it is called osmosis. This creates a new solution when the chemicals within the solvent react to each other creating equilibrium between the different molecules and their concentrations. In order to test this theory, we filled two different beakers, one with a 1% concentration of sucrose and another with 10% concentration, and obtained 4 bags made of dialysis tubing.

When I read until the end, I felt bewildered on “All there is with no thinking” and had a chill down my spine. Since little, I learnt that everything has its nature and force of flow. We need to respect the forces and the nature without purposively altering the force. We accept things are just at it is, it has its nature. These are from the idea of Taoism, “Wu Wei”. It does not mean that we do not need to think before an action, instead, we do not put exaggerated and forceful energy to make something to flow. I also, believe the existence and loss of thing is just a part of nature. When there is born, there will be death too. This is how the nature keep the universe balance. So I agree that we need to feel grateful for the presence that we have, and make full use of the presence.

Chemical equilibrium is the study of change within a chemical reaction and how far it will go to reach a dynamic equilibrium (Burdge). Dynamic equilibrium is defined as the constant movement of species in a chemical reaction, gone to incompletion while the rates of production and consumption are equal (Kf = Kr ) (Burdge). It differs from static equilibrium in that species are constantly being consumed and produced, it is dynamic movement (Fox). The concentration of such species do not change, it remains constant (Fox). The rate at which species are being consumed and produced is known as the equilibrium constant (K) (Burdge). Due to the fact that the concentration

This is an argument between the conceptuality and the practicality of Nash equilibrium in Economics. To understand it we need to first look into what economics is about, which is the study of social and human interaction and rational decision making quantitatively. Nash equilibrium can act as a tool to provide an insight into such interaction. In the first part of this essay, I am going to evaluate why the statement ‘economics without the concept of Nash equilibrium is conceptually flawed’ is true, by looking into the importance of rationality in economics and the mechanism of the Nash equilibrium. In the second part, I am going to assess why the argument for ‘Economics with the concept of Nash equilibrium is practically useless’ is true

Elasticity of demand is shown when the demands for a service or goods vary according to the price. Cross-price elasticity is shown by a change in the demand for an item relative to the change in the price of another. For substitutes, when there is a price increase of an item, there is an increase in the demand for another item. When viewing complements, if there is an increase in the price of an item, the demand for another item decreases. Income elasticity is shown when there is a change in the demand for a good relative to a change in income. This concept is shown in how people will change their spending habits when their income levels change. For
