If the pressure of `N_(2)//H_(2)` mixture in a closed vessel is 100 atmospheres and `20%` of the mixture then reacts the pressure at the same temperature would be .

A

`100`

B

`90`

C

`85`

D

`80`

Text Solution

Verified by Experts

`20 %` mixture reacts to form `10 % NH_(3)` , Thus `80%` mixture and `10 % NH_(3)` left or total pressure left `=90 atm` since `100%` mixture has `100 atm`.
