Calculate the ratio of the mean free paths of the molecules of two gases having … identical conditions of temperature, pressure and…
Mean Free Path:
(1) The distance travelled by a gas molecule between two successive collisions is known as free path.
λ = Total distance travelled by a gas molecule between successive collisions / Total number of collisions
During two successive collisions, a molecule of a gas moves in a straight line with constant velocity.
Let λ1, λ2 , λ3 be the distance travelled by a gas molecule during n collisions respectively, then the mean free path of a gas molecule is given by
