The electrochemical cell shown below is a concentration cell. M|M2+ (saturated solution of a sparingly soluble salt, MX2) | |M2+ (0.001 mol dm–3)|M.
The emf of the cell depends on the difference in concentration of M2+ ions at the two electrodes. The emf of the cell at 298 is 0.059 V. (2012)
The value of ∆G (kJ mol–1) for the given cell is (take 1F = 96500 C mol–1)
