The ratio of root mean square velocity of hydrogen at K 50 to that of nitrogen at K 500 is closest to

A

1.18

B

0.85

C

0.59

D

1.4

Text Solution

Verified by Experts

The correct Answer is:
A
`V_(rms) = sqrt((3RT)/(M))`
`((V_(rms) H_2)/((V_(rms) )O_2) = (sqrt ((3 xx R xx 50)/(2)) )/(sqrt( (3 xx R xx 500)/(28) ) ) = 1.18`
