Question

Write the Nernst equation and explain the terms involved.

Write Nernst equation.

Answer 1

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
