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
- A40.2
- B47.2
- C12.5
- 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
