    In an isothermal process:

    A)  \[\Delta H=\Delta E+P\Delta V\]  

    B)  \[\Delta H=W\]

    C)  \[\Delta H=\Delta E\]       

    D)  \[\Delta H=S\Delta T\]

    Correct Answer: B

    Solution :

     In an isothermal process, the temperature is constant So,           \[\Delta E=0\] Hence \[\Delta H=P\Delta V\] (As,\[\Delta H=\Delta E+P\Delta V\]) \[\Delta H=W\]       (\[\because \]\[W=P\Delta V\])
