Given reaction is,
H2O(l) + CO2(g) g → H2CO3(aq)
Given, ΔHf = -612.96 kJ/mol for carbonic acid,
Temperature = 298.15 K.
ΔHreactn = ?
ΔHreactn = ΔHf
Because the reaction is occurred in standard temperature, 298K.
ΔHreactn = = -612.96 kJ/mol

The carbon dioxide produced in animal cells is transported to the lungs mostly dissolved in blood plasma. Essential to this process is the reaction of CO2 with water. Given the ΔHf = -612.96 kJ/mol for carbonic acid, calculate the ΔHreaction at 298.15 K.
Carbonic acid present in the blood comes mainly from dissolved carbon dioxide (CO2). Dissolved carbon dioxide, CO2(aq), reacts with water to produce H2CO3. a) Write the equilibrium expression for this process. b) The equilibrium constant for this reaction is the hydration constant for CO2, Kh = [H2CO3]/[CO2(aq)] = 3.0 x 10−3 . Combine this equation with the expression you derived in 1.a) for the equilibrium expressions for the first ionization (controlled by Ka1) and rearrange to obtain the apparent equilibrium...
Complete the following sentences describing the reactions of CO2 in plasma. red blood cells carbonic anhydrase low left reversible acidic right cytoplasm basic arrow The concentration of carbon dioxide determines the following reaction: H2O + CO2 + H2CO3 The above reaction is catalyzed by the enzyme carbonic anhydrase found in In the tissues, where CO is high, the reaction will move to the making the blood more making In the lungs where CO2 is low and H2CO3 is high, the...

8. (4 pts) The biological catalyst carbonic anhydrase converts carbon dioxide to carbonic acid, an essential component of the bicarbonate buffer system regulating our blood pH. What mass (in me) of sodium carbonate (NaHCO, MM: 84.006 g/mol) must be added to 500.0 ml of 0.029 M carbonic acid (K. 1 4.3 x 10-7, K., 4.8 x 10-11) to produce a solution with pH = 7.40? Assume no volume change after the addition of sodium carbonate. H2CO3 + H2O=HCO3 + H20...
Carbon dioxide dissolves in water to form carbonic acid, which
is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium
equation The acid dissociation constants listed in most standard
reference texts for carbonic acid actually apply to dissolved CO2.
For a CO2 partial pressure of 1.8×10–4 bar in the atmosphere, what
is the pH of water in equilibrium with the atmosphere? (For
carbonic acid Ka1 = 4.46× 10–7 and Ka2 = 4.69× 10–11).
