Question
Indicate if the following statements are true or false. Clearly justify each and every answer. a) Under fixed pressure the mean free path of a gas increases with temperature. () b) In a mixture of two gases, A and B, the collision frecuency of A against molecules of B, zAB is proportional to the molar fraction of gas A c) Knowing from the Kinetic Theory of gases that ? -(v>??, for two gases at the same temperature, the gas with the larger mass has the highest viscosity. d) Knowing from the Kinetic Theory of gases that D =-(v??, the diffusion constant is proportional to T1/2.Explanation / Answer
The answers are:
a) True
b) True
c) True
d) False.
In case of d mean free path is proportional to T3/2
