Document Summary
Some chemical rxns do not react to completion; ie at any given time during the rxn, there are fixed proportions of both reactants and products. Instead of converting all available reactants into products, these rxns reach equilibrium ; which means the reaction is reversible; ie reactants are converting into products at the same rate that products are switching back into reactants. Different chemical reactions will achieve equilibrium at different points in time and at different. To identify a reaction"s specific equilibrium point, the equilibrium constant keq (upper case) is used. Imagine the reaction aa + bb cc +dd. Keq = solid and liquid substances, by definition, do not have a concentration and are excluded from. Equilibrium law calculations; therefore this calculation only applies to (aq) and (g) The size of k depends on the relative concentrations of the reactants vs. the products at equilibrium. If keq >> 1, therefore products are favoured, products are at a [high] at equilibrium.
