Question

Which of the following is a Nernst equation?

(a) Ecell=E^ocell–RT/nF ln(K)

(b) Ecell=E^ocell–nF/RT ln(K)

(c) E^0cell=Ecell–RT/nF ln(K)

(d) E^0cell=Ecell–nF/RT ln(K)

I had been asked this question during an online interview.

My doubt stems from Corrosion Principles in chapter Corrosion Principles of Corrosion Engineering

Answer 1

The correct option is (a) Ecell=E^ocell–RT/nF ln(K)

Explanation: Ecell=E^ocell–RT/nF ln(K) is the Nernst equation. E^ocell is the potential of a cell in the standard state, R is Universal gas constant, n is the valency of ion, T is absolute temperature, F is Faraday’s constant and K is the reaction quotient, Ecell is the cell potential.
