Cоnsider the reаctiоn between NO аnd Cl2 tо form NOCl: 2 NO(g)+Cl2(g) ⇌ 2 NOCl(g) A reаction 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 NOCl is 0.30 M. Find the value of the equilibrium constant (Kc) at this temperature.
