Chapter 15, Problem 5SAQ

Consider the reaction between NO and Cl₂ to form NOCI.

   $\text{2 NO}\left(\text{g}\right)+{\text{Cl}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons \text{2NOCI}\left(\text{g}\right)$

A reaction mixture at a certain temperature initially contains only [NO] = 0.50 M and [Cl₂] = 0.50 M. After the reaction comes to equilibrium, the concentration of NOCI is 0.30 M. Find the value of the equilibrium constant (K_c) at this temperature.
