An electrochemical cell is shown below `Pt, H_(2)(1 "atm")|HCl(0.1 M)|

1.	An electrochemical cell is shown below `Pt, H_(2)(1 "atm")\|HCl(0.1 M)\|CH_(3)COOH(0.1 M)\|H_(2)(1 "atm")`, The emf of the cell will not be zero, becauseA. The pH of 0.1 M HCl and 0.1 M acetic acid is not the sameB. Acids used in the two compartments are differentC. E.M.F of a cell depends on the molarities of acids usedD. The temperature is constant
Answer» Correct Answer - A `E_("cell") ne 0` because `[H^(+)]` is not same in 0.1 M HCl and 0.1 `M CH_(3)COOH`.
