Question

The equation with the concentrations of the products of a reaction raised to their stoichiometric coefficients divided by the concentrations of the reactants raised to their stoichiometric coefficients.

Answer 1

Explanation:

This is the description of the equilibrium constant equation. For example:

Given a generic reaction: $aA + bB \longleftrightarrow cC+ dD$

Where A.B,C and D are the reactants and products and a,b,c and d are their stoichiometric coefficients. The equilibrium constant of this reaction will be:

$K=\frac{[C]^c*[D]^d}{[A]^a*[B]^b}$

Note: is important to have in mind that the substances in solid or liquid (pure) state should not be included in the K equation.
