Question

Relation between equilibrium constant and standard emf is ?

Answer 1

The Relation between equilibrium constant and standard emf is $E^0=\frac{2.303\times RT\times \log K_c}{nF}$

Explanation:

Relation between gibbs free energy and equilibrium constant

$\Delta G^o=-2.303\times RT\times \log K_c$      (1)

where,

$\Delta G^o$ = Gibbs free energy

R = universal gas constant

T = temperature

$K_c$ = equilibrium constant

Relation between gibbs free energy and emf

$\Delta G^o=-nFE^0$    (2)

$\Delta G^o$ = Gibbs free energy

n= number of electrons gained or lost

F= Faraday's constant

$E^0$  = emf

Equating (1) and (2)

$-2.303\times RT\times \log K_c=-nFE^0$  

$E^0=\frac{2.303\times RT\times \log K_c}{nF}$
