The temperature at which the velocity of oxygen will be half of hydrogen at NTP is

A

`1092^(@)C`

B

`1492^(@)C`

C

`273^(@)C`

D

`819^(@)C`

Text Solution

Verified by Experts

Given , `v_(O_(2))=(1)/(2)V_(H_(2))`
`therefore" " sqrt((3RT)/(32))=(1)/(2)sqrt((3Rxx273)/(2))`
`(T)/(32)=(273)/(8)`
` therefore" " T=4xx273`
`T=1092K=1092-273`
`T=819^(@)C`
