What is the effect of change in (a) concentration, (b) temperature on the electrode potential of a given half-cell?
For a half-cell in which the electrode reaction is,
The Nernst equation is
From the equation, E ∝ T and E ∝ [Mn+]
(a) When the concentration of Mn+ increases, the half-cell potential increases and vice-versa.
(b) When temperature increases, the half-cell potential also increases.
