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

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.

is the pH of water in equilibrium with the atmosphere? (For
carbonic acid Ka1 = 4.46× 10–7 and Ka2 = 4.69× 10–11).
