If a chemical reaction goes to completion, what can we say about the equilibrium constant for that reaction?

a. the equilibrium constant is very large.
b. the equilibrium constant is very small.
c. no right choice.

A. The equilibrium constant is very large

Explanation:

The equilibrium constant value is the ratio of the concentrations of the products over the reactants. When a chemical reaction goes to completion, that means that all the reactant has turned into products. As the equilibrium constant defines, it is the ratio of the product to the reactant. So at the final stage of the chemical reaction, the equilibrium constant will be very large.
