If we start with 8.00 g carbon powder (gr graphite, solid, MW 12.01 g/mol) and 0.500 M hydrogen in a 2.85 L container and heat the reaction to 225°C, after 3 hours we find we have 0.100 M hydrogen left. Has the system reached equilibrium, if not, in which direction is it still proceeding? 3C(gr) + 4H2(g) <-> C3Hg(g) Kc = 2.70 M3
