select the correct answer. how is the enthalpy of reaction shown in this potential energy diagram? a. as the sum of the energy of the products and the energy of the reactants b. as the sum of the activation energy and the energy of the products c. as the difference of the energy of the reactants and the energy of the products d. as the difference of the activation energy and the energy of the products

Answer

Brief Explanations:

The enthalpy of a reaction ($\Delta H$) is defined as the difference between the energy of the products ($E_p$) and the energy of the reactants ($E_r$), i.e., $\Delta H=E_p - E_r$. In a potential - energy diagram, it is shown as the vertical distance between the energy level of the products and the energy level of the reactants.

Answer:

C. as the difference of the energy of the reactants and the energy of the products
