When calcium oxide react with carbon dioxide to form calcium carbonate then carbon dioxide would react as a Lewis acid in the reaction.
A chemical species known as a Lewis acid has an empty orbital that can accept a pair of electrons from a Lewis base to produce a Lewis adduct.
In the reaction, orbital of carbon dioxide will be vacant orbital that's why it can be considered as Lewis acid.
Its reaction can be written as:
[tex]CaCO_{3}[/tex] → CaO +[tex]CO_{2}[/tex]
It is kind of decomposition reaction.
