Question

variations of enthalpy of a reaction with temperature​

Answer 1

Answer:

Hey Buddy here's ur answer

Kirchhoff's Law describes the enthalpy of a reaction's variation with temperature changes. In general, enthalpy of any substance increases with temperature, which means both the products and the reactants' enthalpies increase. The overall enthalpy of the reaction will change if the increase in the enthalpy of products and reactants is different.

with

c↓p is the (assumed constant) heat capacity and

H↓Ti and H↓Tf are the enthalpy at the respective temperatures.
