The kinetic energy of 1 g molecule of a ...

The kinetic energy of 1 g molecule of a gas, at normal temperature and pressure, is

A

` 1.3 xx 10J`

B

` 2.7 xx 10 ^(2) J`

C

` 0.56 xx 10 ^(2) J`

D

` 3.4 xx 10 ^(3)J`

Text Solution

Verified by Experts

The correct Answer is:
D
Kinetic energy (per mol )= ` (f)/(2) RT`
` K = (3)/(2) RT`
Now , when nothing said about the atomicity of gas, goes for translational kinetic energy
` K= (3)/(2) xx 8.31 xx 273`
`= 3.14 xx 10^(3) ` Jule
