Substituting the values as:
So, the amount of NO and Cl2 is 3.0 M and 1.0 M respectively.
As the value of K is very small so the reverse reaction can be assumed to proceed to completion and generation of NOCl takes place.
Since, the ratio of NO:Cl2is 3:1 instead of 2:1 so, Cl2 will limit the production of NOCl that is Cl2 is the limiting reagent. So, the Cl2 will react completely and amount of NO reacted will be 3.0 − 2.0 = 1.0 M and amount of NOCl formed will be 2.0 M.

Since, the ratio of NO:Cl2is 1:1 instead of 2:1 so, NO will limit the production of NOCl that is NO is the limiting reagent. So, the NO will react completely and amount of Cl2 reacted will be 1.0 − 0.5 = 0.5 M and amount of NOCl formed will be 1.0 + 1.0 = 2.0 M.
