How does the value of kc in n2o4(g)⇋2no2(g) kc=[no2]2[n2o4] depend on the starting concentrations of no2 and n2o4?

Answer;

The value of Kc does not depend on starting concentrations.

Explanation;At constant temperature, changing the equilibrium concentration does not affect the equilibrium constant, because the rate constants are not affected by the concentration changes. When the concentration of one of the participants is changed, the concentration of the others vary in such a way as to maintain a constant value for the equilibrium constant.
