The reaction of NO (g) + Cl2 (g) ⇌NOCl (g) + Cl (g) is found to have an equilibrium constant of 1.1*108 at a particular temperature. What does this mean? Question 1 options: 1) At equilibrium, there is a much higher concentration of reactants than products. 2) At equilibrium, there is a much higher concentration of products than reactants. 3) At equilibrium, there is an equal concentration of reactants and products. 4) At equilibrium, the value of the equilibrium constant depends on the initial concentration (s).

Option (2) At equilibrium, there is a much higher concentration of products than reactants.

Explanation:

The equilibrium constant for a reaction is simply the ratio of the concentration products raised to their mole ratio divided by the concentration of the reactants raised to their mole ratio.

If the equilibrium constant is close to 1 or 1, it means the concentration of the reactants and products are almost the same. But if the equilibrium constant is large as in the case of the question given above, it means that at equilibrium, the concentration of the products are higher than that of the reactants.
