Question

Derive the expression for equilibrium constant with the help of nernst equation

Answer 1

Answer:

Nernest equation is the one which relates the cell potential and the concentration of the species involved in an electrochemical reaction. Let us consider an electrochemical cell for which the overall redox reaction is, xA + yB = lC + mD The reaction quotient Q is, We know that, ∆G = ∆G0 + RT ln Q ∆G = – nFEcell ∆G0 = -nFE0 cell equation (1) becomes – nFE = -nFE0 + RT ln Q Subsitutute
