Question

The net energy released or absorbed during a reversible chemical reaction is equal to

Answer 1

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

Answer 2

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 $\Delta H_{rxn}$

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

$\Delta H_{rxn}=\sum H_{products}-\sum H_{reactants}$

where,

$H_{products}$ = Potential energy of the products

$H_{reactants}$ = Potential energy of the reactants

Hence, the correct answer is Option 3.
