Solution


Q.

Consider the graph of Gibbs free energy G vs extent of reaction. The number of statement/s from the following which are true with respect to points (A), (B) and (C) is ______.
  [2023]

A. Reaction is spontaneous at (A) and (B)
B. Reaction is at equilibrium at point (B) and non-spontaneous at point (C)
C. Reaction is spontaneous at (A) and non-spontaneous at (C)
D. Reaction is non-spontaneous at (A) and (B)

Ans.

(2)

Reaction is spontaneous in a direction in which Gibbs free energy decreases. Hence, two statements i.e. B and C are correct.
