Question

Is a graph that starts at 25 and drops to 21, stays the same in temperature an endothermic reaction or an exothermic reaction?

Answer 1

Step-by-step explanation:

Endo and Exo thermic are defined by what changes take place in the environment of the reaction.

If the temperature goes up, the reaction is giving up heat. It is Exothermic.

If the temperature goes down, the reaction requires heat. It is Endothermic.

In this case, the temperature went down. The reaction is Endothermic.
