The heat of reaction__________________?
Correct answer: B. Is independent of the mechanism of reaction
- A. Depends on the pressure only
- B. Is independent of the mechanism of reaction
- C. Depends on both pressure and mechanism of reaction
- D. Depends on the mechanism of reaction only
Explanation
The heat of reaction is a state-function difference between products and reactants, so it does not depend on the reaction mechanism or the sequence of steps used. Its value can depend on the thermodynamic state and temperature, but not on the pathway.
