Question
Which of the following is not correct?
Options
∆G is zero for a reversible reaction
∆G is zero for a reversible reaction
∆G is negative for a spontaneous reaction
∆G is positive for a non-spontaneous reaction
Solution
∆G is zero for a reversible reaction
Explanation:
∆G gives a criterion for spontaneity at constant pressure and temperature.
(i) If ∆G is negative (< 0). the process is spontaneous.
(ii) If ∆G is positive (> 0). the process is non-spontaneous.
(iii) If ∆G is zero then reaction is at equilibrium.
