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....
