MCQ
The enthalpy change of a reaction does not depend on
  • A
    The state of reactants and products
  • B
    Nature of reactants and products
  • ✓
    Different intermediate reaction
  • D
    Initial and final enthalpy change of a reaction
✓

Answer

Correct option: C.
Different intermediate reaction
c
Enthalpy change is a state function so it does not depend on the path taken by the reaction. it depends only on the difference of final and initial values of enthalpy change.
