a. heat of reaction
b. entropy of the reaction
c. activation energy of the forward reaction
d. activation energy of the reverse reaction

Answer 1

Answer:

a. heat of reaction

Answer 2

In a potential energy diagram, the difference between the potential energy of the products and the potential energy of the reactants is equal to the heat of reaction.

What is heat of the reaction?

Heat of the reaction gives idea about the nature of the reaction means the exothermic or endothermic nature of reaction.

Heat of reaction = Energy of product - Energy of reactant

If the energy of product is more than the reactant energy then the reaction is endothermic in nature and if the energy of the reactant is more than the product then the reaction is exothermic in nature.

• Entropy of the reaction gives idea about the arrangement so it is wrong.
• Activation energy gives idea about the ease of the completion of reaction, so it is also wrong.

Hence potential energy diagram shows the heat of reaction.
