For the following with hydrogen electrodes at two different pressures p1 and p2:

\(\underset{\mu_{1}}{\operatorname{Pt}\left(H_{2}\right)}\left|\mathrm{H}_{1 \mathrm{M}}^{+}(\mathrm{aq})\right| \mathrm{Pt}\left(\mathrm{H}_{2}\right)\)

emf is given by:

  1. \(\frac{\mathrm{RT}}{\mathrm{~F}} \log _{\mathrm{R}} \frac{\mathrm{P}_{1}}{\mathrm{P}_{2}}\)
  2. \(\frac{\mathrm{RT}}{\mathrm{ZF}} \log _{\mathrm{R}} \frac{\mathrm{P}_{1}}{\mathrm{P}_{2}}\)
  3. \(\frac{\mathrm{RT}}{\mathrm{~F}} \log _{\mathbf{r}} \frac{\mathrm{P}_{\mathbf{2}}}{\mathrm{P}_{1}}\)
  4. \(\frac{\mathrm{RT}}{\mathrm{ZF}} \log _{\mathrm{R}} \frac{\mathrm{P}_{2}}{\mathrm{P}_{1}}\)

Answer

(B) RT ZF _ R P _ 1 P _ 2
