$Pt ∣ H_{2} (1 atm) ∣ H^{+} (pH = 2) ∥ H^{+} (pH = 3) ∣ H_{2} (1 atm) ∣ Pt$

The cell reaction for the given cell is:

Options:

Answer:

Solution:

As the [H⁺] increases, the reduction potential of hydrogen electrode increases. The reduction potential of anode half−cell is greater than that of cathode half−cell. The emf of the given cell will be negative. Therefore, the cell reaction is non− spontaneous.
