Explanation:

DECOMPOSITION REACTION IS A REACTION IN WHICH THE COMPOUND SPLITS UP INTO TWO OR MORE SIMPLER SUBSTANCES.

THERE ARE GENERALLY THREE TYPES OF DECOMPOSITION REACTION:-

1.) THERMAL DECOMPOSITION :-

=> WHEN THE DECOMPOSITION REACTION IS CARRIED OUT BY HEATING IT IS CALLED AS THE THERMAL DECOMPOSITION REACTION.

FOR EXAMPLE:-

2FeSO4----HEAT---->FeO3+SO2+SO3

2.)ELECTROLYTIC DECOMPOSITION REACTION:-

THOSE DECOMPOSITION REACTION WHICH ARE CARRIED OUT BY IN THE PRESENCE OR BY THE USE OF ELECTRICITY THEY ARE KNOWN AS THE ELECTROLYTIC DECOMPOSITION REACTION.

FOR EXAMPLE:-

2H2O--E-L-E-C-R-I-C-I-T--Y--->2H2 +O2

OR YOU CAN SIMPLY WRITE ELECTROLYSIS OF WATER.

3.)PHOTOLYTIC DECOMPOSITION REACTION:-

THOSE REACTION WHICH ARE CARRIED OUT UNDER THE LIGHT (LIKE SUNLIGHT ETC.) ARE KNOWN AS THE PHOTOLYTIC DECOMPOSITION REACTION.

FOR EXAMPLE:-

2AgCl-H-E-A-T------>2 Ag+Cl2.
