double displacement reaction is when two high
reactive metal displace the two less reactive metal from their aqueous solution exNA2SO4+K2CO3-K2SO4+NA2CO3 displacement reaction is when the more reactive metal displace the low reactive metal.

Here's your answer....
Double replacement reactions—also called double displacement, exchange, or metathesis reactions—occur when parts of two ionic compounds are exchanged, making two new compounds. The overall pattern of a double replacement reaction looks like
A+B−+C+D−→A+D−+C+B
You can think of the reaction as swapping the cations or the anions, but not swapping both since you would end up with the same substances you started with. The solvent for a double replacement reaction is usually water, and the reactants and products are usually ionic compounds—but they can also be acids or bases.
Example---
PB(NO3)2 + 2KI----------------->PbI2 + 2 KNO3
difference between displacement and double displacement
Single replacement: one element replaces another element of its own kind in a compound (metals replace metals, non-metals replace non-metals). A+BC = B+AC (A and B are cations) or A+BC = C + BA (A and C are anions).
Double replacement: two aqueous compounds exchange their positive and negative ions resulting in two new compounds. AB+CD = AD+CB (A and C are positive ions, B and D are negative ions).
