Final answer:

The chemical reaction represented by the equation is a double replacement reaction.

Step-by-step explanation:

The chemical reaction represented by the equation Pb(NO₃)₂ (aq) + 2 KI (aq) → 2 KNO₃ (aq) + PbI₂ (s) is a double replacement reaction. In a double replacement reaction, the cations and anions of two different compounds switch places, resulting in the formation of two new compounds.
