Question

Enlist any two types of reactions which do not involve the principle of reactivity series for product formation​

Answer 1

Single and Double reaction

Answer 2

The two types of reactions which do not involve the principle of reactivity series for product formation​ are:

(1) COMBUSTION REACTIONS.

- Combustion takes place when a compound undergoes oxidation to produce heat and a new product.

- For Example:

C + O2 → CO2 + Heat

(2) DECOMPOSITION REACTIONS.

- Decomposition occurs when a chemical compound splits up into a no of new compounds on supplying energy.

- For example:

CaCO3 + energy → CaO + CO2

• Both the above reactions do not involve any principle of reactivity series.
