The logarithm of the equilibrium constant of the cell reaction corresponding to the cell X ( s ) | X 2 + ( a q ) | | Y + ( a q ) | Y ( s ) with standard cell potential, E o c e l l = 1.2 V is given by

Options

  1. A40.2
  2. B47.2
  3. C12.5
  4. D21.5

Correct answer

A. 40.2

Step-by-step solution

E o = 0.0591 n l o g K e q So, logK eq = E o × n 0.0591 = 1.2 × 2 0.0591 = 40.6
