Question

A cell has a standard emf of + 0.135 v at 298 k. part a what is the value of the equilibrium constant for the cell reaction if n=1?

Answer 1

To look for the value of the equilibrium constant for the cell where n=1, it is computed by:
Eo = RT / nF * ln(K) 
(Eo * nF) /RT = ln(K) 
(0.135 * 1mol* e- * 9.65E4C/mol*e) / (8.314J / molK * 298K) = ln(K) 
10.52 = lnK 
e^10.52 = e ^ lnK 
K = e ^263/25
K = 37049.12 is the answer.
