Question

For the electrochemical cell, M|M+||X−|X, $E_{M^{+}|M}^{o}$= 0.44 V and $E_{X|X^{-}}^{o}$= 0.33 V. From this data, one can deduce that

Options

A.M + X → M+ + X− is the spontaneous reaction
B.M+ + X− → M + X is the spontaneous reaction
C.Ecell = 0.77 V
D.Ecell = − 0.77 V

Solution

$E_{cell}^{o} = 0.44 - 0.33 = 0.11\text{ V}$
