Question
How is an endothermic reaction identified?A.It requires heat as a reactant.B.It results in a phase change.C.It has a large heat capacity.D.It gives off heat as a product.
Solution
An endothermic reaction is identified by option A: It requires heat as a reactant. This means that the reaction absorbs heat from its surroundings. This is in contrast to an exothermic reaction, which releases heat. Options B, C, and D are not specific identifiers of an endothermic reaction. A phase change can occur in both endothermic and exothermic reactions, heat capacity is a property of substances involved but not a definitive identifier, and giving off heat as a product is characteristic of an exothermic, not endothermic, reaction.
