Dear Salma,

Here is the required solution to your problem.

The question you asked is related to electrochemistry.Here E0 stand for standard emf of cell,G0 stand for standard Gibbs energy and Keq is equilibrium consatnt so the relationship between these will be as-

E=-E0-RT/nF log Keq

Here f is farrady constant 1F=96500c

Thank you

All the very best.
