Question

According to Hess's law, the heat of reaction depends upon

• A. initial condition of reactants
• B. initial and final conditions of reactants
• C. intermediate path of the reaction
• D. end conditions of reactants

Answer 1

The correct option is B initial and final conditions of reactants

According to Hess's law, the heat of reaction depends upon Initial and final conditions of reactants. The the heat of reaction is independant of the intermediate path of the reaction. For example, the heat of the reaction for the reaction $A\to D$ is equal to the sum of the heats of the reactions $A\to BB\to CC\to D$
