Dear Deeksha,

The standard electrode potentials are given at standard conditions. However, real cells may operate under non-standard conditions. Given the standard potential of the half-cell, its potential at non-standard effective concentrations can be calculated using the Nernst Equation:

$E_{\text{half-cell}} = E^\circ - \frac{RT}{nF}\ln Q$
