Question

Though nitrogen does not support combustion, it controls the rate of combustion. Give reasons for the statement.

Answer 1

Nitrogen -

1. It is a diatomic gas found in the air.
2. The molecular formula of nitrogen is N₂.
3. The nitrogen gas is non-reactive under normal conditions.
4. It does not participate in processes like respiration, photosynthesis, and combustion.

Role of nitrogen in controlling rate of combustion -

1. The high atmospheric concentration of nitrogen creates an environment that prevents unnecessary combustion processes.
2. The presence of nitrogen limits the supply of oxygen to combustion and keeps it under control.
