Question

Given, $\Delta G^{\circ}=-n F E^{\circ}$ cell and $\Delta G^{\circ}=-R T \ln k$. The value of $n=2$ will be given by the slope of which line in the figure

• A. OA
• B. OB
• C. OC
• D. OD

Answer 1

Answer: (B)

$-n F E_{\text {cell }}^{\circ}=-R T \ln k$ or $E_{\text {cell }}^{\circ}=\frac{R T}{n F} \ln k .$
Plot of $\ln k$ or $E_{\text {cell }}^{\circ}$ will have slope $=\frac{1}{2} \frac{R T}{F}$
