For the reaction the standard free energy is The equilibrium constant (K) would be,
(i) K = 0
(ii) K > l
(iii) K = 1
(iv) K < 1
The answer is the option (iv) K < 1
Explanation: As lnK and so if , then is negative, which means K<1. This certainly implies that a non-spontaneous reaction or a reaction proceeds in the forward direction to such a small degree that only a very small quantity of product is formed.
