  Which of the following in not correct? (a)\[\Delta G\]is zero for a reversible reaction                    (b)\[\Delta G\] is positive for a spontaneous reaction (c)\[\Delta G\]is negative for a spontaneous reaction     (d)\[\Delta G\]is positive for a non-spontaneous reaction

Answer:

  (b) \[\Delta G\text{ }<\text{ }0\](For spontaneous process) \[\Delta G\text{  }0\] (For non-spontaneous process) \[\Delta G\text{ = }0\] (For reversible process at equilibrium)
