. 450 cm3 of nitrogen monoxide and 200 cm3 of oxygen are mixed together and ignited


450 cm3 of nitrogen monoxide and 200 cm3 of oxygen are mixed together and ignited. Calculate the composition of resulting mixture.

2NO + O2 2NO2

 

Best Answer

2NO + O2 →2NO2

2 V 1 V 2 V

From equation, 1V of O2 reacts with = 2 V of NO

200cm3 oxygen will react with = 200 ×2 =400 cmNO

Hence, remaining NO is 450 - 400 = 50 cm3

NO2 produced = 400cm3 because 1V oxygen gives 2 V NO2

Total mixture = 400 + 50 = 450 cm3
