Question

State Hess Law of constant heat summation and illustration it with the help of example.​

Answer 1

Answer:

Hess's law of heat summation states that the total enthalpy change during a reaction is the same whether the reaction takes place in one step or in several steps. For example, in the above diagram, ΔH1=ΔH2+ΔH3=ΔH4+ΔH5+ΔH6 .
