Unformatted text preview: Most chemical reactions are reversible. The arrow below indicates that the reaction is reversible. CO 2 + H 2 O ↔ H 2 CO 3 In the reaction above, carbonic acid (H 2 CO 3 ) accumulates when the concentration of CO 2 is high. A higher concentration of CO 2 produces a faster reaction due to more frequent molecular collisions. At low CO 2 concentration, the reaction moves toward the left, causing carbonic acid to break down and form CO 2 + H 2 O. An equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction....
