Question : 64 of 85

Marks: +1, -0

The equation

4 {\NH}_3+5 {\O}_2 → 4 {\NO}+

6 {\H}_2 {\O}

, represents the catalytic oxidation of ammonia. If

100 {\cm}^3

of ammonia is used calculate the volume of oxygen required to oxidise the ammonia completely.

Solution:

4 {\NH}_3+5 {\O}_2 → 4 {\NO}+6 {\H}_2 {\O}

4 \Vol. : 5 \Vol.

If 4 volumes of

{\NH}_3

requires

5 {\vol}

. of

{\O}_2

Then

100 {\cm}^3

{\NH}_3

requires

=\;{5}/{4} × 100

=125 {\cm}^3 \;\text " oxygen. "\;
