The most probable speed of 8 g of `H_(2)` is `200 ms^(-1)`. Average kinetic energy (neglect rotational and vibrational energy ) of `H_(2)` gas is :

A

480 J

B

240 J

C

120 J

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
b
(b) `200=sqrt((2RT)/(2xx10^(-3))=RT=40`
`"Average K.E."=(3)/(2)nRT=(3)/(2)xx(8)/(2)xx40`
`=240J`
