Once equilibrium has been established, both forward and reverse reactions are still taking place. Once products have been formed, both the forward and reverse reactions are taking place. Equilibrium constant ( K eq ) is equal to the following: [Products]/[Reactants] - Remember to include in exponent form the coefficients in front of the products and/or reactants. K a , K b , and K sp are all examples of equilibrium constants Solids and pure liquids are NOT included within this expression - Why? Their concentrations do not change. If the reaction is gaseous, we can use the partial pressure of each gas as its concentration. Memorize the following relationships: If K eq < 1, then the reaction favors the reactants If K eq = 1, then the reaction balances reactants and products If K eq > 1, then the reaction favors the products Relate to: ΔG = -RT ln ( K eq ) - If ΔG is negative, that means K eq is positive, and the reaction favors the products (i.e. spontaneity) - ΔG = 0, then the reaction is at equilibrium - ΔG is positive, then K eq is negative, and the reaction favors the reactants. What are some things that indicate equilibrium has been reached? -
