Question

Consider the following cell:

Where pHA is the pH of the aqueous solution in the anode half-cell and pHC is the pH of the aqueous solution in the cathode half-cell. If the partial pressure of H2(g) is the same for both half-cells, (p1 = p2), then E for the cell at 25°C is
A) 0.0296 V log (pHA/pHC).
B) 0.0296 V log (pHC/pHA).
C) 0.0592 V (pHA - pHC).
D) 0.0592 V (pHC - pHA).
