Question

The enthalpy change for a reaction does not depend upon:

• A. use of different reactants for the same product
• B. the nature of intermediate reaction steps
• C. the differences in initial or final temperatures of involved substances
• D. the physical states of reactants and products

Answer 1

The correct option is B the nature of intermediate reaction steps

Enthalpy change is a state function and depends upon the initial and final states but not on the path. Therefore, the enthalpy change for a reaction does not depend upon the nature of intermediate reaction steps.
