    A system is changed from an initial state to a final state by a manner such that\[\Delta H=q\]. If the change from the initial state to the final state were made by a different manner then \[\Delta H\]remains same but q changes because

    A) \[\Delta H\]is a path function and q is a state function

    B) \[\Delta H\]is a state function and q is a path function

    C)  Both\[\Delta H\]and q are state function

    D)  Both\[\Delta H\]and q are path function

    Correct Answer: B

    Solution :

                    Enthalpy change, ie,\[\Delta H\]is a state function, ie, depends only upon the initial and final states, not upon the path followed. While heat, q is a path function, ie, depends upon the path followed.
