Question

Write the Nernst equation and explain the terms involved

Answer 1

Nernst equation can be given as,

E = E⁰ - \(\frac{2.303\,RT}{nF}log_{10}\,\frac{[Products]}{[Reactants]}\)

where,

E⁰ = 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
