An electrochemical cell is set up as follows: $Pt(H_2, 1 \, atm) | 0.1 \, M \, HCl || 0.1 \, M \, CH_3COOH | (H_2, 1 \, atm) Pt$. The $E.M.F.$ of this cell will not be zero because:
- AThe $pH$ of $0.1 \, M \, HCl$ and $0.1 \, M$ acetic acid is not the same.
- BAcids used in two compartments are different.
- C$E.M.F.$ of a cell depends on the molarities of acids used.
- DThe temperature is constant.
