The averge translational kinetic energy ...

The averge translational kinetic energy of `8g` methane at `27^(@)C` is .

A

`3.1xx10^(-21) J`

B

`6.2xx10^(-21) J`

C

`4.2xx10^(-21) J`

D

`8.4xx10^(-21) J`

Text Solution

Verified by Experts

Average `K.E = (3)/(2) xx (R )/(N) xx T`
` =(3)/(2) xx (8.314)/(6.023 xx 10^(23)) xx 300`
`= 6.21 xx 10^(-21) J` .
