your question is incomplete.
The standard enthalpy of reaction (denoted ΔrH⊖) is the enthalpy change that occurs in a system when one mole of matter is transformed by a chemical reaction under standard conditions.
Lets discuss the factor on which enthalpy change depends:-
(1)state of the reactant and product
(2)It is a state function.It depends only upon the initial and final state.
