Question

Consider the following reaction:  This reaction:

Quizplus · Accepted Answer

The reaction is not specified, so we cannot determine the specific enthalpy change. However, the fact that the question states "Consider the following reaction" implies that we are given a reaction that is known to be endothermic. Therefore, A is the best choice. B is not necessarily true without further information about the specific reaction. C is the opposite of what would occur in an endothermic reaction, as heat would be absorbed from the surroundings, making them cooler. D is partially true, but incomplete, as the conversion of chemical energy into thermal energy is a general result of any exothermic or endothermic reaction.
