In a gaseous 2L reaction system, 2.00 mol of methane, CH4(g) is added to 10.00 mol of chlorine, Cl2(g). At equilibrium, the system contains 1.40 mol of chloromethane, CH3Cl(g), as well as some hydrogen chlorine, HCI(g).
a) State a balanced chemical equation for this equilibrium.
b) Compute the amount of each substance at equilibrium.
