Calculate the equilibrium constant (Kc) for the reaction between nitrogen gas (N2) and hydrogen gas (H2) to form ammonia gas (NH3) at a temperature of 400 K. The reaction is written as follows: N2(g) + 3H2(g) ⇌ 2NH3(g) Given the equilibrium concentrations are [N2] = 0.10 M, [H2] = 0.20 M, and [NH3] = 1.0 M.
