- Identify the first chemical step in the production of Portland cement. How is this reaction related to the chemistry that takes place in the carbonation of concrete?What is the activated Complex in a heating curve ? O The amount of energy needed to raise the temperature of 1 gram of any substance 1 degree Celsius. O the point phase diagram where a substance will exists as a solid, liquid, and gas at the same time. O Makes the reaction happen faster. OThis point is the temporary unstable arrangement of atoms where old bonds are broken and new bonds are forming.Apply collision theory to explain why powdered zincreacts to form hydrogen gas faster than large pieces ofzinc when both are placed in hydrochloric acid solution.
- Explain An exothermic reaction— how the energies of the transition stateand products are related ?The collision theory is used to predict the rate of chemical reactions. It assumes that for a reaction to occur, what two things must occur? It is necessary for the reacting species to come together with the right amount of energy. It is necessary for the reacting species to come together with the right geometric orientation. It is necessary for the reacting species to be covalent molecules. It is necessary for the reacting species be ionic compounds.The minimum amount of energy needed by the reactant to form the activated complex and lead to a reaction is known as the enthalpy. True or false
- an energy needed to form complex reaction is calledWhat is the total potential energy content of the activated complex?An activated complex (transition state) is: (Choose one) and please explain. A. A substance that acts to increase the rate of a raction without itself being consumed.B. A stable molecule that is formed during an early step of a reaction, and consumed in a later step. C. A substance that forms during a reaction that has a definite, well-known structure. D. The arrangement of atoms at the top of the potential energy barrier.E. A molecular species with normal chemical bonds that is produced during a reaction.
