Question

For the following reaction at 2025 K, equal numbers of moles of H2, NH2, and HCN, and an excess of graphite (C) are allowed to come to equilibrium: H2(g) + N2(g) + 2C(s) = 2HCN(g) Explain why each of the following statements are true or false in 1-2 sentences. No calculations necessary. a) The equilibrium amount of HCN will increase if the volume is decreased. b) The amounts of H2 and N2 will always remain in equimolar proportions as they decrease from the initial concentration to the equilibrium concentration. c) The amount of graphite is the same as the initial amount. d) Total gas pressure will remain constant as the system moves from initial conditions to equilibrium.
