Unformatted text preview: Determine the direction of a reaction, given K and the concentrations of all reactants and products. Use an equilibrium table to calculate K, equilibrium composition, and the initial concentrations of reactants and products. Explain how the value of the reaction quotient, Q, allows the direction of reaction to be predicted. Use Le Chatelier's principle to predict how the equilibrium composition of a reaction mixture is affected by: adding or removing reagents; compressing or expanding a gaseous mixture; and by raising or lowering the temperature....
