At constant pressure, the heat capacity is equal to change in enthalpy divided by the change in temperature.
Therefore, if the heat capacities do not vary with temperature then the change in enthalpy is a function of the difference in temperature and heat capacities. The amount that the enthalpy changes by is proportional to the product of temperature change and change in heat capacities of products and reactants.
This is stated by Kirchoff's Law.

The variation of the heat of reaction with temperature is given by Kirchoff's equation;
(△H2−△H1)/(T2−T1)=△CP.
(△H2−△H1)/(T2−T1)=△CP.
