For the electrochemical cell, (M | M+) || (X- | X), Eo = (M+ | M) = 0.44V and Eo(X | X-) = 0.33V
From this data one can deduce that :
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
Ecell = EoO.P.M/M+ + EoR.P.X/X-
= - 0.44 +0.33 = - 0.11V
M + X → M+ + X-. Thus reaction is non-spontaneous. The spontaneous reaction in
M+ + X- → M + X; Eo = 0.11V
= - 0.44 +0.33 = - 0.11V
M + X → M+ + X-. Thus reaction is non-spontaneous. The spontaneous reaction in
M+ + X- → M + X; Eo = 0.11V
