Adding a catalyst to a chemical system does not affect the equilibrium position, but it does impact the overall rate of reaction. A catalyst works by providing an alternative reaction pathway with a lower activation energy, which allows the reaction to proceed more quickly. However, it does not change the relative energy levels of the reactants and products, so the equilibrium constant remains the same.In the Haber process, nitrogen N2 and hydrogen H2 react to form ammonia NH3 :N2 g + 3H2 g 2NH3 g The equilibrium constant K for this reaction is given by:K = [NH3]^2 / [N2] * [H2]^3 where [NH3], [N2], and [H2] represent the equilibrium concentrations of ammonia, nitrogen, and hydrogen, respectively.Let's assume we have an initial concentration of 1.0 M for N2 and 3.0 M for H2, and no NH3 present. After the reaction reaches equilibrium, we can represent the change in concentrations as follows:[N2] = 1.0 - x[H2] = 3.0 - 3x[NH3] = 2xNow, let's say the equilibrium constant K is 0.5 for illustration purposes . We can plug the concentrations into the equation for K:0.5 = 2x ^2 / 1.0 - x * 3.0 - 3x ^3 Solving this equation for x, we find that x 0.29. This means that at equilibrium, the concentrations are:[N2] 1.0 - 0.29 = 0.71 M[H2] 3.0 - 3 0.29 = 2.13 M[NH3] 2 0.29 = 0.58 MNow, let's introduce a catalyst to the system. As mentioned earlier, the catalyst will not change the equilibrium constant K, so the equilibrium concentrations will remain the same. However, the rate at which the reaction reaches equilibrium will be faster due to the lower activation energy provided by the catalyst.In summary, adding a catalyst to a chemical system, such as the Haber process, will increase the overall rate of reaction, allowing the system to reach equilibrium more quickly. However, it will not change the equilibrium position or the equilibrium constant.
