Which of the following statements is true?
| The energy of the starting materials for a reaction equals the sum of the product energies plus energy released as heat and disorder. |
| The entropy of the products of a reaction is always greater than the entropy of the starting materials. |
| The entropy of the starting materials for a reaction is always greater than the entropy of the products. |
| The amount of useable energy resulting from a reaction is never less than the total energy available in the starting materials. |
Homework Answers
Statements first and second are true.
Option 1. Energy conservation rule.
Option 2. According to Rules of thermodynamics.. Entropy always increses.
Option 3. Refer option 2 (Entropy of products will be higher)
Option 4.Usable energy decrese as there is no ideal energy conversion method. (Interesting read- Karnot engine principle)

Classify each of the statements as true or false. True False Answer Bank The entropy of a substance increases when a liquid vaporizes to a gas at any temperature. Entropy decreases as the temperature increases. An exothermic reaction is always spontaneous. Product formation is always favored in a reaction with a negative AH° and a negative AS. For an endothermic reaction, a decrease in temperature results in a decrease in the equilibrium constant. A reaction will have an equilibrium constant...
