Question

Diffusion of a chemical is faster in air than in water because?

Answer 1

The high intermolecular spaces and low intermolecular forces between the gas particles result in faster diffusion compared to liquid particles.

To answer this problem, we must define what a simple diffusion is. Simple diffusion is the movement of molecules from an area of high concentration to an area of low concentration. We can understand the movement of gases at the molecular level through the kinetic-molecular theory of gases. Some of its assumptions include the following:

1. Gaseous particles are separated by distances far greater than their particle dimensions. This means that there are high intermolecular spaces between the particles.
2. Gas molecules are in constant motion in random directions, and they frequently collide with one another.
3. The collision between gas particles as well as the container wall is elastic. This means that there is no energy loss and the total energy of the system remains the same.
4. Gas molecules do not exert either attractive or repulsive forces on one another, which means that there is a low intermolecular force between them.

Based on these assumptions, gas particles are considered to move at a higher speed resulting in faster diffusion compared to liquid particles.
