Question

For a reversible reaction at 298 K the equilibrium constant $K$ is 200 . What is the value of $\Delta G^{\circ}$ at 298 K ?

Professor PC Thomas Classes · Answer

(c) :Applying $\Delta G^{\circ}=-2.303 R T 	imes \log K$ 
$ =-2.303 	imes 2 	imes 298 	imes \log 200=-3158.4 \mathrm{cal}=-3.158 \mathrm{kcal} $
