The hemoglobin equilibrium is described by this equation: $$Hb(aq) + O_2(g) \rightleftharpoons HbO_2(aq)$$ a. Decreasing the concentration of one of the reactants shifts the equilibrium in the direction of the reactants. b. Increasing the concentration of one of the reactants shifts the equilibrium in the direction of the products. c. Decreasing the concentration of one of the products shifts the equilibrium in the direction of the products.
