# A student investigates the gas-phase synthesis of ammonia represented by the following equation.

\[\text{N}_2(g) + 3\,\text{H}_2(g) \rightleftharpoons 2\,\text{NH}_3(g)\]

A mixture of \(\text{N}_2(g)\) and \(\text{H}_2(g)\) is introduced into a rigid, evacuated \(2.0\text{ L}\) container at a constant temperature. Once equilibrium is established, the container holds \(0.40\text{ mol}\) of \(\text{N}_2(g)\), \(0.20\text{ mol}\) of \(\text{H}_2(g)\), and \(0.60\text{ mol}\) of \(\text{NH}_3(g)\). What is the value of the equilibrium constant, \(K_c\), for the reaction at this temperature?
