The Heat of Reaction (also known and Enthalpy of Reaction) is the change in the enthalpy of a chemical reaction that occurs at a constant pressure. It is a thermodynamic unit of measurement useful for calculating the amount of energy per mole either released or produced in a reaction. this can be solve by PE of product - PE of reactants

The heat of reaction has been given by [tex]\Delta H=PE_{product}-PE_{reactant}[/tex].

Thus, option A is correct.

Potential energy has been defined as the energy possessed by the molecules in the resting condition. The kinetic energy has been given as the energy possessed by the molecules in motion.

Heat of reaction for a Chemical reaction

The heat of reaction has been defined as the amount of energy gained or released by the system during the chemical reaction.

The chemical reaction has been given by the change in the potential energy of the product and the reactant.

Thus, the heat of reaction has been given by:

[tex]\Delta H=PE_{product}-PE_{reactant}[/tex]. Thus, option A is correct.
