A) the physical state of the reactants and products
B) the temperature of the reaction
C) the number of moles of reactants
D) the path by which the reactants are converted into products
Correct Answer: D
Solution :
The enthalpy change, \[\Delta H=\Delta E+\Delta n\,.\,RT\]. From the equation, it is clear that enthalpy of reaction depends upon temperature, the physical states of reactant and products and on the number of moles. But according to Hesss law of constant heat summation enthalpy of reaction does not depend on the path followed to convert reactants into products.
