Consider the following cell: Pt(s) ∣ H2(g,p1) ∣ H+(aq,pHA) ∣∣ H+(aq,pHC) ∣ H2(g,p2) ∣ Pt(s)
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) .
