Solution

The correct option is C $C l_{2} (g) + 2 N O (g) ⇌ 2 N O_{2} C l (g); K_{c} = 1.8$
For the reaction of the option C $(C l_{2} (g) + 2 N O (g) ⇌ 2 N O_{2} C l (g); K_{c} = 1.8)$ , the value of the equilibrium constant is around 1. In such a case, appreciable amounts of reactants and products are present.
