Part a determine the expression for the equilibrium constant, kc, for the reaction by identifying which terms will be in the numerator and denominator: kc=numeratordenominator=? ? place the terms into the appropriate bin.

In Kc expression, the concentration of product is always placed at numerator while the concentration of reactant are place in denominator.

Explanation:

Kc is a equilibrium constant which is dependent on concentrations of reactants and products and is defined as.

               Kc = [product]÷[reactant]

Consider a reaction

                  A + B > C + D

So its Kc expression will be as

               Kc = [C].[D] ÷[A].[B]

Summary :

The concentrations of product are always place at numerator while concentration of reactant are place in denominator.

idk i’m struggling too
