Select the correct answer.
How is the enthalpy of reaction shown in this potential energy diagram?
ОА.
as the sum of the energy of the products and the energy of the reactants
OB.
as the sum of the activation energy and the energy of the products
Ос.
as the difference of the energy of the reactants and the energy of the products
OD.
as the difference of the activation energy and the energy of the products
m. All rights reserved.

H= energy of product minus energy of reactant

H is endothermic and positive when heat is absorbed

H is exothermic and negative when heat is released

You forgot to attach the diagram but I have an idea of what it might look like. So since the energy of reactant is at a lower level and energy of product is at a higher level, the reaction will be positive.

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