(MARK ALL THAT APPLY) O More energy is required to start the reaction than is released by the reaction itself. O Less energy is required to start the reaction than is released by the reaction itself. O The more stored energy a substance has the less chemically stable it is. O The more stored energy a substance has the more chemjcally stable it is. O The reactants have less stored energy than the products. O The reactants have more stored energy than the products. O The reactants are more chemically stable than the products. O The reactants are less chemically stable than the products.

Which of the following statements about the storage of energy using chemical systems are correct? Mark all that are true. A. When energy is stored in a system where Q > K, energy is released from storage when the forward reaction occurs. B. Storing energy in a chemical system requires taking the system away from equilibrium. C. If AG° is negative, the forward reaction will always release energy and the reverse reaction will always store energy. D. The energy available by carrying out the forward reaction will change unless we take some additional action to hold Q constant.

In order to break water into hydrogen and oxygen, water is heated to more than 500°C. Which kind of reaction is this and why? It is exothermic because heat needs to be released by the reactants to form the products. It is endothermic because heat needs to be released by the reactants to form the products It is exothermic because heat needs to be absorbed by the reactants to form the products. It is endothermic because heat needs to be absorbed by the reactants to form the products.
