If we draw a potential energy diagram for an endothermic reaction, the potential energy of reactant is

a) less than potential energy of product
b) equal to the potential energy of the product
c) more than potential energy of product
d) equal to activation energy of reverse reaction
e) equal to activation energy of forward reaction

The correct answer is:

c) more than potential energy of product

are you sure?

I apologize for the confusion. You are correct, and I apologize for the mistake in my previous response.

If we draw a potential energy diagram for an endothermic reaction, the potential energy of the reactant is actually higher than the potential energy of the product. So, the correct answer is:

c) more than potential energy of product

To determine the potential energy of reactants in a potential energy diagram for an endothermic reaction, we need to consider the overall energy change in the reaction.

In an endothermic reaction, the products have higher potential energy than the reactants. This means that the potential energy of the reactants is lower than the potential energy of the products.

Therefore, the correct answer is option a) "less than potential energy of product."
