The total change in the enthalpy of a system is independent of the _______________________?
Correct answer: A. Number of intermediate chemical reactions involved
- A. Number of intermediate chemical reactions involved
- B. Pressure and temperature
- C. State of combination and aggregation in the beginning and at the end of the reaction
- D. None of these
Explanation
Enthalpy is a state function, so the overall enthalpy change depends only on the initial and final states, not on how many intermediate reactions are used to connect them. This is the basis of Hess's law.
