Answer:
The equilibrium concentration of carbonic acid will increase.
Step-by-step explanation:
CO₂ (g) + H₂O (l) ⇄ H₂CO₃ (l)
The Le Chatelier rule states that the reaction will shift in order to reestate the equilibrium.
If the pressure of carbon dioxide increases, the the equilibrium will shift towards the consumptiom of carbon dioxide. This means that more carbonic acid will be produced.
