उत्तर
Nernst equation can be given as,
`E = E^circ - (2.303 RT)/(nF) log_10 [["Products"]]/[["Reactants"]]`
where,
E° = Standard potential of electrode or cell,
n = Number of moles of electrons used in reaction,
F = Faraday = 96500 C/mol e−,
[Products] = Concentration of products,
[Reactants] = Concentration of reactants,
T = Temperature in K and
R = Gas constant = 8.314 J K−1 mol−1
