26. Statement: The potential for the cell, Pt|Ha(g. latm)HCI)JAgCI(s)]Ag(s) decreases as the concentration of HCI is increased. Reason: The mean ionic activity coefficient decreases with increase in HCI concentration Assertion: In a plot of E vs [HCI], the intercept at the potential axis is equal to the standard reduction potential of the hydrogen electrode. (a) Both Reason and Assertion are correct (b) Both Reason and Assertion are wrong () Reason is correct but Assertion is wrong (d) Reason is wrong but Assertion is correct.
