Question

For the following cell with hydrogen electrodes at two different pressure p₁ and p₂. What will be the emf for the given cell :

$$\eqalign{ & Pt({H_2})|{H^ + }(aq)|Pt({H_2}) \cr & \,\,\,\,\,{p_1}\,\,\,\,\,\,\,\,\,\,\,\,\,\,1M\,\,\,\,\,\,\,\,\,\,\,\,{p_2} \cr} $$

${{RT} \over F}{\log _e}{{{P_1}} \over {{P_2}}}$

${{RT} \over 2F}{\log _e}{{{P_1}} \over {{P_2}}}$

${{RT} \over F}{\log _e}{{{P_2}} \over {{P_1}}}$

none of these
