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