We are asked to determine the value of the equilibrium constant, K for the cell reaction given its standard emf and number of electrons transferred, n at 298 K.
The Nernst Equation relates the equilibrium constant and cell potential and is given by the equation:
E°cell = cell potential, V
R = gas constant = 8.314 J/(mol·K)
T = temperature, K
n = mole e- transferred
F = Faraday’s constant, 96485 C/mol e-
K = equilibrium constant
A cell has a standard emf of + 0.151 V at 298 K.
What is the value of the equilibrium constant for the cell reaction if n = 3?
