[2015]

(a) $\Delta G=2.30$ $ R T $ $\log K$

(b) $\Delta G^{0}=-2.30 $ $R T $ $\log K$

(c) $\Delta G^{0}=2.30 $ $R T$ $ \log K$

(d) $\Delta G=-2.30 $ $R T$ $ \log K$

Show Answer

Answer:

Correct Answer: 18.(b)

Solution:

  1. (b) $\Delta G^{\circ}=-2.30$ $ R T$ $ \log K$

because at equilibrium $\Delta G=0$
