57. Solving a chemistry problem

139. Why does the equilibrium of the N2 3H2 = 2NH3 system shift when pressure changes and the equilibrium of the N2 O2 = 2NO system does not shift? Justify your answer based on the calculation of the rate of forward and reverse reactions in these systems before and after the pressure change. Write expressions for the equilibrium constants of each of these systems.
