For the equilibrium reaction of carbon dioxide with water, what is the appropriate equation?

H2O + CO2 ⇌ H2CO3

H2O + CO2 ⇌ H2CO

H2O + 2CO2 ⇌ H2CO3

H2O + CO ⇌ H2CO3

H2O + CO2 ⇌ H2CO3

Option 1

Explanation:

Decomposition for the carbonic acid produces water and carbon dioxide.

As this reaction is an equilibrium we can write in both senses:

For this case:

Reactants: Water and CO₂

Products: H₂CO₃

The reaction is: H₂O + CO₂  ⇄  H₂CO₃
