Solution

The correct options are
A Initial concentration of $N_{2} O_{4}$
C Pressure of catalyst
D Pressure
Only a temprature change can force a equilibrium constant to change. If we can the pressure or the initial concentration the equilibrium concentration of reactant and product may change but equlibrium constant remains the same.
