Reversible reaction to consider: CO2(g) + H2O(l) + Na+(aq)+Cl-(aq)= HCO3(aq) +H+(aq)+Cl-(aq) Note: This reaction models atmospheric CO2 which dissolves in the ocean in a reversible reaction. Answer the following questions: 1. From an equilibrium perspective, what happens to the pH of the ocean when the concentration of CO2 in the atmosphere increases? 2. What affect on equilibrium would occur if some Na is removed from the reaction? 3. If the pH of the ocean was lowered by adding a large quantity...
The enzyme carbonic anhydrase catalyzes the reaction CO2(g)+H2O(l)−→−HCO3−(aq)+H+(aq).CO2(g)+H2O(l)→ HCO3−(aq)+H+(aq). In water, without the enzyme, the reaction...
The enzyme carbonic anhydrase catalyzes the reaction CO2(g)+H2O(l)−→−HCO3−(aq)+H+(aq).CO2(g)+H2O(l)→ HCO3−(aq)+H+(aq). In water, without the enzyme, the reaction proceeds with a rate constant of 0.039s−10.039 s−1 at 25°C.25 °C. In the presence of the enzyme in water, the reaction proceeds with a rate constant of 1.0×106s−11.0×106 s−1 at 25°C.25 °C. Assuming the collision factor is the same for both situations, calculate the difference in activation energies for the uncatalyzed versus enzyme- catalyzed reaction.

1) why is CO2 the conjugate acid of bicarbonate? Please explaing CO2 (g) + H2O(l) ⇄ H2CO3 (aq) 2) Exercise increases metabolism and thus increase the amount of CO2 in the blood. Following a bout of intense exercise, the pH of your blood was found to be 7.1 and the HCO3− concentration in the blood to be 8 mM. Remember the overall reaction for the bicarbonate buffering system in the blood can be written as: H2CO3 (aq) ⇄ HCO3- (aq)...

Now, for a complete equilibrium problem Consider the following general reaction: HC2H3O2 (aq) + H2O (l) ⇌ H3O+ (aq) + C2H3O2–(aq) Kc = 1.8 x 10–5 (at 25 ºC) If a solution initially contains (7.9x10^-1) M of HC2H3O2, (and no H3O+ or C2H3O2– ), what is the equilibrium concentration of H3O+ (aq) in the mixture? In the appropriate blanks, provide the equilibrium [H3O+ (aq)], in the solution, in M, to two significant figures and to the appropriate power
