The moles of `O_(2)` required for reacting with 6.8 ammonia
`(...N H _(3) + ... O _(2) to ... NO + ... H _(2) O )` is

A

5

B

`2.5`

C

1

D

`0.5`

Text Solution

Verified by Experts

The correct Answer is:
D
The balanced equation is
`4 NH _(3) + 5 O _(2) to 4 NO + 6 H _(2) O`
From the equation, `4 xx 17 ` of `NH _(2)` require `O _(2) = 5` mol
6.8 of `NH _(3)` require `O _(2)`
`= ( 5 xx 6.8)/(4 xx 17) = 0.5 ` mol
