Solution: When carbon dioxide dissolves in water, it undergoes a multistep equilibrium process, with Koverall = 4.5 x 10−7, which is simplified to the following: CO2(g) + H2O(l) ⇌ H2CO3(aq) H2CO3(aq) + H2O(l) ⇌ HCO3−(aq) + H3O+(aq)(a) Classify each step as a Lewis or a Brønsted-Lowry reaction.

Problem

When carbon dioxide dissolves in water, it undergoes a multistep equilibrium process, with Koverall = 4.5 x 10−7, which is simplified to the following: 

CO2(g) + H2O(l) ⇌ H2CO3(aq) 

H2CO3(aq) + H2O(l) ⇌ HCO3(aq) + H3O+(aq)

(a) Classify each step as a Lewis or a Brønsted-Lowry reaction.
