Question

Which of the assumptions of the kinetic-molecular theory best explains Dalton's law of partial pressures?

The velocity of gas molecules is proportional to their Kelvin temperature.

Gas molecules move at random with no attractive forces between them.

In collisions with the walls of the container or with other molecules, energy is conserved.

Collisions with the walls of the container or with other molecules are elastic.

The amount of space occupied by a gas is much greater than the space occupied by the actual gas molecules

Explanation / Answer

Ans : Gas molecules move at random with no attractive forces between them.

According to the Dalton's law of partial pressures , the non reacting gases have no forces of attraction or repulsion in between their particles. They exert pressure on the walls of container as the result of their collisions.
