OverviewWhat is Q?Using Q to predict the direction of reactionVisualizing QExampleSummaryThe reaction quotient Q is a measure of the relative amounts of products and reactants present …For reversible reaction aA+bB⇌cC+dD , where a , b , c , and d are the stoichiometric coefficients for the balanced reaction, we can calculate Q using the following equation:Q=[C]c[D]d[A]a[B]b This expression might look awfully familiar, because Q is a concept that is closely related to the equilibrium constant K . Unlike K , which is based on equilibrium concentrations, Q can be calculated whether we are at equilibrium or not.
