There are a series of steps that someone must go through to determine equilibrium constants for reactions at chemical equilibrium. The first step is to write a balanced chemical equation. However, before the chemical equation can be written, the reaction must be at equilibrium. Next, an equilibrium expression has to be written. In order to write the equilibrium expression the product concentrations are placed in the numerator while the reactant concentrations are placed in the denominator. However, there are species to be left out and these include the concentration of a pure liquid or any solid. This is because the concentrations never change. Additionally, water will be omitted for any reaction that occurs in aqueous solution because water’s
