CO 2 (g) CO 2 (aq.) How does a plant trap CO 2 if the reaction is not favorable? CO 2 (aq.) + H 2 O (l) H 2 CO 3 (aq.) H 2 CO 3 (aq.) + H 2 O (l) H 3 O + (aq.) + HCO 3 - (aq.) Dissolution Reaction Acid-Base K eq =0.8317 K eq = 3.09 X 10 -5 K eq = 4.46 x 10 -6 CO 2 in the atmosphere cannot produce required cellular levels How can the cell shift the position of the equilibrium???
