A chemistry student needs to determine the equilibrium constant (Kc) for the reaction: N2(g) + 3H2(g) ⇌ 2NH3(g)At a certain temperature, 0.2 mole of nitrogen gas (N2), 0.3 mole of hydrogen gas (H2), and 0.4 mole of ammonia gas (NH3) were placed in a 1 L container. Using these initial concentrations, what is the equilibrium constant (Kc) for the reaction?
