Find the ratio of the mean speed of hydrogen molecules to the mean speed of nitrogen molecules in a sample containing a mixture of the two gases.

A

` sqrt(14)`

B

` sqrt7`

C

` sqrt(28) `

D

None of these.

Text Solution

Verified by Experts

The correct Answer is:
A
` v_(avr)= vec V = sqrt((8RT)/(pi M)) `
` (vec V _(H_2)) /(vec V_(N_2)) ` = sqrt((1//2)/(1//28)) = sqrt((14)/(1))`
