What is the equilibrium constant of a reaction? a. it is the ratio of the concentrations of products to the concentrations of reactants. b. it is the ratio of the number of moles of products to the number of moles of reactants. c. it is the concentrations of products multiplied by the concentrations of reactants. d. it is the number of moles of reactants subtracted from the number of moles of products.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
