Identify all statements below that are characteristics of a single microstate OR of all microstates as they pertain to entropy at the molecular level: I. A microstate defines the state – solid, liquid, or gas – of a small cluster of atoms or molecules. II. A single microstate is a unique specification of all the electronic, vibrational, rotational, and translational energy levels in a system. III. A single microstate is a unique specification of the vibrational, rotational, and translational states of all the particles/molecules in a system. IV. All microstates that are populated at a given time must have the same overall energy as the system. Select one: a. IV only b. I and III c. I and II d. II only e. I only f. I and IV g. Il and III h. THREE of them are correct O i. III and IV V j. All FOUR of them are correct k. Il only I. Il and IV
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
III and IV are correct. Please specify why each of the 4 statements are correct and incorrect
