The best definition of the enthalpy of reaction, ∆H is that energy absorbed or released by a system during a reaction (option A).

What is enthalpy of reaction?

Enthalpy in chemistry is a measure of the heat content of a chemical or physical system.

Specifically, the enthalpy of reaction denoted by ∆H is the change in the enthalpy of a chemical reaction that occurs at a constant pressure.

It can also be described as the amount of heat evolved or absorbed in a chemical reaction when the number of moles of the reactants as represented by the chemical equation have completely reacted.

Therefore, it can be said that the best definition of the enthalpy of reaction, ∆H is that energy absorbed or released by a system during a reaction (option A).
