question 101

Multiple Choice

Consider the following cell: Pt(s) ∣ H₂(g,p₁) ∣ H⁺(aq,pH_A) ∣∣ H⁺(aq,pH_C) ∣ H₂(g,p₂) ∣ Pt(s)
Where pH_A is the pH of the aqueous solution in the anode half-cell and pH_C 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 (pH_A/pH_C).
• B)0.0296 V log (pH_C/pH_A).
• C)0.0592 V (pH_A - pH_C).
• D)0.0592 V (pH_C - pH_A).
