MHT CET 2024 Chemistry question

Identify the factor from following on which heat of reaction does not depend

(A)Physical states of reactants and product
(B)Total number of steps in which reaction occursCorrect
(C)Temperature of the reaction
(D)Weather the reaction is carries out at constant pressure or constant volume

Answer: (B)

Solution

Enthalpy is a state function, so by Hess's law the heat of a reaction depends only on the initial and final states and not on the path or the number of steps by which the change occurs. Hence it does not depend on the total number of steps, option (B). It does depend on the physical
