Which of the following statements is /are not true?

Options

A. Most prabable velocity `prop =sqrt((3RT)/(m))`
B. `PV=(2)/(3)kT`
C. Compressibility factor `Z=(PV)/(nRT)`
D. Average kinetic energy of a gas `=(1)/(2)kT`

Explanation

(A) Most probable velocity `=prop =sqrt((2RT)/(m))`
(D) Average kinetic energy of a gas `=(3)/(2)kT`
Hence, (A) and (D) are the correct answer.
