Answer:
            This equation represents a Double Displacement Reaction.

Explanation:
                    
Given equation is,

                                      AB + CD    AD + CB

In above reaction A and C are switching their groups i.e. B and D. A has given off B to C and C has given D to A. Such reactions in which the cations and anions of two compounds are exchanged are called double displacement or double replacement reactions.
