The equilibrium between carbon dioxide gas and carbonic acid is very important in biology and environmental science, and is shown below.CO₂(aq) + H₂O(l) ⇌ H₂CO₃(aq)
Based on the equilibrium constant reported for this reaction (K_c = 1.70 * 10^-3), there will be more carbon dioxide in solution than carbonic acid.

Question

Quizplus · Accepted Answer

The equilibrium constant (K) for the reaction CO2(aq) + H2O(l) ⇌ H2CO3(aq) is small (1.70 × 10^-3), indicating that the reaction favors the reactants (CO2 and H2O) over the product (H2CO3), meaning there will be more CO2 in solution than carbonic acid at equilibrium.
