Consider the following reaction:  This reaction:

Quizplus · Accepted Answer

In an endothermic reaction, energy is absorbed from the surroundings, resulting in a positive ΔH value. Since the given reaction has no given value of ΔH, we cannot determine whether it has a negative or positive value. However, we can determine that the reaction is endothermic because the products have more energy than the reactants, meaning energy has been absorbed. Choice B is incorrect since there is no given indication of the sign of ΔH. Choice C is incorrect because an endothermic reaction actually makes the surroundings cooler, not warmer. Choice D is incorrect since the given reaction is not converting chemical energy into thermal energy, but instead, it is the reverse-thermal energy is being absorbed into the system.
