\huge\textbf{Decomposition Reaction}

When a more reactive element displaces less reactive element from it's compound. Such type of reaction is known as Displacement Reaction.

i.e.

AB + C -----› AC + B

\textbf{Ex :}

2Al (s) + 3CuCl2 (aq) ----› 2AlCl3 (aq) + 3Cu (s)

When Aluminium (Al) react with Copper Chloride (CuCl2) then Aluminum Chloride (AlCl3) and Copper (Cu) is produced.

\textbf{Reactivity Series}

Potassium = K [High Reactivity Series]

Sodium = Na

Calcium = Ca

Magnesium = Mg

Aluminum = Al

Zinc = Zn

Iron = Fe

Lead = Pb

Hydrogen = H

Copper = Cu

Silver = Ag

Gold = Au [Low Reactivity Series]

\underline{Note}

From the above reactivity series Aluminum (Al) is more reactive than Copper (Cu). That's why it displaces Copper Chloride (CuCl2) from it's compound and form new compound.
