Question

Which statement is true about the potential energy diagram for an exothermic reaction? aThe products have less potential energy than reactants. bThe energy value remains the same throughout the diagram. cThe graph starts at a lower energy value and ends at a higher energy value. dThe potential energy of the products is equal to the potential energy of the reactants.

Answer 1

Explanation:

Please, look at the next picture:

According to the graph, it is known that the reactants have higher potential energy than the products.

Here the reactants are A + B and the product is C.

Answer: a The products have less potential energy than reactants.
