Question

Looking at the potential energy diagram below, is the reaction taking place endothermic, exothermic, or both?


1. Both, because heat is being absorbed since the potential energy is decreasing.

2.Both, because heat is being released and absorbed since the potential energy is decreasing.

3.Endothermic, because heat is being absorbed since the potential energy is decreasing.

4.Endothermic, because heat is being released since the potential energy is decreasing.

5.Exothermic, because heat is being absorbed since the potential energy is decreasing.

6.Exothermic, because heat is being released since the potential energy is decreasing.

Answer 1

(6) Option It's an exothermic reaction, as we know the decrease in the potential energy indicates the increase in the kinetic energy and thus release of heat.
