Question #78242
The equation ΔHo = Σ ΔHfo (products) – Σ ΔHfo (reactants) stands for _______.
A. the First Law of Thermodynamics
B. the Second Law of Thermodynamics
C. Gibbs Free Energy Law
D. Hess’s Law
E. None of the Above
A. the First Law of Thermodynamics
B. the Second Law of Thermodynamics
C. Gibbs Free Energy Law
D. Hess’s Law
E. None of the Above
Expert's answer
Answer:
Correct answer is D. The equation stands for Hess's law, i.e. the change of enthalpy in a chemical
reaction is independent of the pathway between the initial and final states, and therefore calculated
as a difference between sum of enthalpy of formation of products and reactants.
