Write the equation showing the effect of concentraconcentra on the electrode potential.

Are you referring to the Nernst Equation? It can tell you the electrode potential under non-standard conditions.

E = E^o + (RT) / (zF) + log₁₀ [oxidised form] / [reduced form]

Where E^o = standard electrode potential for that cell
R= The gas constant, 8.31 J K^-1 Mol^-1
T= Temperature in Kelvin
z= Number of moles of electrons transferred in the equation
F= The Faraday Constant, roughly 96500 C mol^-1
log= log to the base of 10
[oxidised form] = concentration of the oxidised form in the reduction half equation
[reduced form] = concentration of the reduced form in the reduction half equation
