The Maxwell velocity distribution indicates that


a.the total translational kinetic energy of all of the molecules in a sample of an ideal gas is (3/2)(kT)(V).
b.the mean velocity of the molecules in a sample of an ideal gas in any one direction is zero.
c.molecules of an ideal gas move with the same velocity at a given temperature regardless of molecular mass.
d.it is impossible to know the mean velocity of the molecules in the sample.


e. the energy of a molecule of an ideal gas depends more on its position than on its velocity.

b.
The velocity includes the direction. The average of the velocity, therefore, should be zero since there is no preferred direction for the random assortment of speeds to be traveling
