Question

Define thermal decomposition reaction explain with an example

Answer 1

Answer:

When the decomposition of a substance is carried out by using heat, it is known as thermal decomposition reaction.

OR

If the heat is used for decomposition of the compound, it is called thermal decomposition reaction.

Example :

• CaCo3 ---∆--- Cao + Co2 .
• 2Pb(NO3)2 ---∆--- 2Pbo2 + 4NO2 .

( sign ∆ represent the symbol of heating)

Hope you find it easy.
