Q. $\mathrm{\Delta}G{^\circ}$for the reaction $X + Y \rightleftharpoons Z$ is $- 4.606$ kcal. The value of equilibrium constant of the reaction at $227℃$ is $(R = 2.0\ cal\ mol^{- 1}K^{- 1})$

A) 100
B) 10
C) 2
D) 0.01
Explanation

(a)
$\mathrm{\Delta}G = - 2.303\ RT\log K$
$- 4.606 = - 2.303 \times 0.002 \times 500\log K$
$\log{K = 2,\ K = 100}$
