Question
An equilibrium reaction has a Kc of 2.7 × 106. Which of the following accurately describes the chemical equilibrium for this reaction?
The concentrations of the products are approximately the same as the concentrations of the reactants.
The concentrations of the reactants are less than the concentrations of the products. The equilibrium is said to favor the reactants.
The concentrations of the products are greater than the concentrations of the reactants. The equilibrium is said to favor the products.

Explanation / Answer
If Kc is greater than 1 —> There are more products than reactant
If Kc is less than 1 —> There are less products than reactant
If Kc is equal to 1 —> Both reactant and products are present in equal amount
Here Kc is less than 1. So, there are more reactants than product
Answer: The concentrations of the products are less than the concentrations of the reactants. The equilibrium is said to favor the reactants.
