Question

In the absence of a catalyst, ammonia burns in an excess of oxygen to produce stream and nitrogen. What is the volume of oxygen remaining when 60 cm3 of ammonia is burnt in 100 cm3 of oxygen, all volume being measured at the same temperature and pressure?
(a) 35 cm3
(b) 40 cm3
(c) 45 cm3
(d) 55 cm3​

Answer 1

The combustion of ammonia proceeds to yield nitogen gas and water. With the use of catalyst and under correct conditions of temperature, ammonia reacts with oxygen to produce nitric oxide which is oxidized to nitrogen dioxide and is used in the synthesis of nitric acid.
