Hess's law of constant heat summation is based on conservation of mass. It deals with ___________________?
Correct answer: B. Changes in heat of reaction
- A. Equilibrium constant
- B. Changes in heat of reaction
- C. Reaction rate
- D. None of these
Explanation
Hess’s law states that the heat or enthalpy change of a reaction is independent of the route and depends only on the initial and final states. Its foundation is conservation of energy, not conservation of mass.
