The equilibrium constant expression for the given system is

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by

For a general chemical reaction:

The is written as:

The concentration of pure solid and pure liquid are taken as 1 in equilibrium expression.

The for the given reaction is written as:

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
