• Chemical Thermodynamics

The enthalpy change for a reaction does not depend upon the

1. use of different reactants for the same product.
2. nature of intermediate reaction steps.
3. physical states of reactants and products.
4. difference in initial or final temperatures of involved substances.

Solution

Hess's Law of Constant Heat Summation states that regardless of the multiple stages or intermediate steps of a reaction, the total enthalpy change for the reaction is the sum of all changes.

The enthalpy of a chemical process is independent of the path taken from the initial to the final state.

The correct option is B.
