The standard potentials of the two half-cells A++, A** | Pt and B**, B* | Pt are Ej and E, respectively. If E2 is greater than E, answer the following. (i) The cell Pt | A**(m), A()+(km) B+)+(n), B³(kn) | Pt was constructed, where k has some constant value. The cell was operated reversibly up to its exhaustion point, i.e. to a point where no more reaction in the cell takes place and hence no more current can be withdrawn from the cell. Show that (a) the half-cell potentials at the exhaustion point are given by the expression nE + ME (n + m) (b) The value of k at the exhaustion point at 298 K is given by the relation nm(E-E) (0.059 13 V)(m + n) logk (ii) Which of the following two cells will give a spontaneous cell reaction when k The standard potentials of the two half-cells A++, A** | Pt and B**, B* | Pt are Ej and E, respectively.
