Question

Which statement is true about the potential energy diagram for an exothermic reaction? (5 points)

Answer 1

Products have less potential energy than reactants.

Step-by-step explanation:

Let's remember the concept of an exothermic reaction: a chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings are gaining heat from the system, the temperature of the surroundings increases.

Now, let's see how looks a potential energy diagram for an exothermic reaction:

This represents that the products have less potential energy than reactants.
