Which of the following relationship is/are not true ?

Answer»

Most prabable velocity `prop =sqrt((3RT)/(m))`
`PV=(2)/(3)kT`
Compressibility factor `Z=(PV)/(nRT)`
AVERAGE KINETIC energy of a gas `=(1)/(2)kT`

Solution :(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.
