The net energy released or absorbed during a reversible chemical reaction is equal to
(1) the activation energy of the endothermic reaction
(2) the activation energy of the exothermic reaction
(3) the difference between the potential energy of the products and the potential energy of the reactants
(4) the sum of the potential energy of the products and the potential energy of the reactants

c. The differencece between the potential energy of the products and the potential energy of the reactants

Answer: The correct answer is Option 3.

Explanation:

The net energy absorbed or released in a chemical reaction is known as the total enthalpy change of the reaction. It is written as [tex]\Delta H_{rxn}[/tex]

The formula used to calculate total enthalpy of the reaction is:

[tex]\Delta H_{rxn}=\sum H_{products}-\sum H_{reactants}[/tex]

where,

[tex]H_{products}[/tex] = Potential energy of the products

[tex]H_{reactants}[/tex] = Potential energy of the reactants

Hence, the correct answer is Option 3.
