MCQ

The incorrect expression among the following is :

A
$\frac{{\Delta {G_{system}}}}{{\Delta {S_{total}}}} = - T$
B
In isothermal process, $w_{reversible} =-nRT \,ln\,\frac{V_f}{V_i}$
✓
$\ln K = \frac{{\Delta {H^o} - T\Delta {S^o}}}{{RT}}$
D
$K=e^{-Delta ^o/RT}$

✓

Answer

Correct option: C.

$\ln K = \frac{{\Delta {H^o} - T\Delta {S^o}}}{{RT}}$

c
$\Delta G^{\circ}=\Delta H^{\circ}-T \Delta S^{\circ}$

$-R T \ell n K=\Delta H^{\circ}-T \Delta S^{\circ}$

$\ell n K=-\frac{\Delta H^{\circ}-T \Delta S^{\circ}}{R T}$
