Question

Which of the following is not correct? (a) ∆G is zero for a reversible reaction. (b) ∆G is positive for a spontaneous reaction (c) ∆G is negative tor a spontaneous reaction (d) ∆G is positive for a non-spontaneous​

Answer 1

Explanation:

Explanation:(b) ∆G gives a criterion for spontaneity at constant pressure and temperature.

Explanation:(b) ∆G gives a criterion for spontaneity at constant pressure and temperature.(i) If ∆G is negative (< 0). the process is spontaneous.

Explanation:(b) ∆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 positiv e (> 0). the process is non-spontaneous.

Explanation:(b) ∆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 positiv e (> 0). the process is non-spontaneous.(iii) If ∆G is zero then reaction is at equilibrium.
