Answer: The correct answer is Option 3.

Explanation:

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

It is defined as the difference between the total potential energy of the products and the total potential energy of the reactants. The equation for this is given by:

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

where,

[tex]\Delta H_{products}[/tex] = Total potential energy of the products

[tex]\Delta H_{reactants}[/tex] = Total potential energy of the reactants

Hence, the correct answer is Option 3.
