Consider a gas confined to a container that can be divided into two compartments of equal volume. If one compartment initially contains N1 identical molecules at energy E1 and the other compartment contains N2 identical molecules at energy E2, what is the probability that the molecules will eventually be distributed equally between the two compartments? Use statistical mechanics and thermodynamic ensembles to calculate this probability.

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.
