Question

When a gas jar containing air is inverted over a gas jar containing bromine vapours, the red brown bromine vapour diffuses into air '. Explain how bromine vapours diffuses into air.

Answer 1

Due to the diffusion process the particles of bromine vapour get mixed with the air particles.

Answer 2

Molecules of a gas has high kinetic energy and therefore, they tend to move rapidly from one place to another. Hence, gases has the ability to diffuse at a faster rate. As a result, bromine vapors diffuse into air due to their high kinetic energy.
