Why does equilibrium constant not change with the Presence of a catalyst ?

The equilibrium constant for a reacton N_(2)(g)+O_(2)(g)=2NO(g) is 4xx10^(-4) at 2000 K . In the presence of catalyst, the equilibrium constant is attained 10 times faster. The equilibrium constant in the presence of catalyst, at 2000 K is

The activation energy of a first order reaction at 300 K is 60 kJ mol^-1 . In the Presence of a Catalyst, the activation energy gets lowered to 50 kJ mol^-1 at 300 K. How many times the reaction rate changes in the Presence of a catalyst at the same temperature ?

Assertion : The enthalpy of reaction remains constant in the presence of a catalyst. Reason : A catalyst participating in the reaction, forms different activated complex and lowers down the activation energy but the difference in energy of reactant and product remains the same.

In Haber’s process, hydrogen is obtained by reacting methane with steam in presence of NiO as catalyst. The process is known as steam reforming. Why is it necessary to remove CO when ammonia is obtained by Haber’s process?
