Question:

A 1.00 mol sample of NOCl was placed in a 2.00 L reactor and heated to 227 $^\circ$ C until the system reached equilibrium. The contents of the reactor were then analyzed and found to contain 0.056 mol of Cl₂. Calculate K at this temperature. The equation for the decomposition of NOCl to NO and Cl₂ is as follows:
$$2NOCl(g) \rightarrow 2NO(g) + Cl_2(g)$
