Assertion: The emf of a cell is related with equilibrium constant of the cell reaction as E_(cell)=(0.0591)/(n)log" "K. Reason: As E_(cell) changes with concentration of the electrodes, K of cell reaction also changes with concentration.

Answer»

If both assertion and reason are true, and reason is the true EXPLANATION of the assertion
if both assertion and reason are true, but reason is not the true explanation of the assertion.
if assertion is true, but reason is false.
If both assertion and reason are false.

Solution :CORRECT A. Correct relation is
`E_(cell)^(@)=(0.0591)/(N)"LOG "K`.
Correct R. equilibrium constant is constant at constant temperature and does not change with concentration.
