True/False: For a given transfer of energy, a greater change in entropy occurs when the temperature is high.
| False, because as temperature decreases there is a greater change in entropy. |
| False, because only heat flow affects the change in entropy, not temperature. |
| True |
Homework Answers
True. Since when the substance is at higher temperature, it has higher entropy and when it gets transferred there is greater loss of entropy.
In a substance at lower temperature, the entropy change is not that large during transfer of energy.

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...
