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.
