Problem

For the electrochemical cell,

M | M^+ || X^- | X

E_{(M^+/M)}^{\circ} = 0.44 \text{ V}

and

E_{(X/X^-)}^{\circ} = 0.33 \text{ V}

. From this data one can deduce that : (IIT 2000) (1)

M + X \longrightarrow M^+ + X^-

is the spontaneous reaction (2)

M^+ + X^- \longrightarrow M + X

is the spontaneous reaction (3)

E_{\text{cell}} = 0.77 \text{ V}

(4)

E_{\text{cell}} = -0.77 \text{ V}
