How much would the equilibrium constant (Kc) change if a catalyst is added to the reaction system, given the initial concentration of reactants and products? Specifically, consider the equilibrium reaction: N2(g) + 3H2(g) ⇌ 2NH3(g)with an initial concentration of N2 = 0.10 M, H2 = 0.20 M, and NH3 = 0.25 M. The activation energy of the reaction is 150 kJ/mol and the catalyst lowers it by 50 kJ/mol. Calculate the change in Kc for this reaction when the catalyst is added to the system.

If the equilibrium constant (Kc) for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g) at a certain temperature is 4.0×10^-3, and a catalyst is added to speed up the reaction, how will the equilibrium position shift? Calculate the new equilibrium constant if the catalyst increases the rate of the forward reaction by a factor of 10.
