Question

Assuming that the all volume is measured at the same temperature and pressure, state the volume ratios of the reactants and products for the following gaseous reactions. Nitrogen reacting with oxygen to form nitrogen (III) oxide.

• A. 1 : 3 : 2
• B. 2 : 4 : 2
• C. 2 : 2: 1
• D. 2 : 3 : 2

Answer 1

Answer: (D)

2 : 3 : 2

The equation for the reaction between nitrogen and oxygen to form Nitrogen (lll) oxide is written as:
$2N_2+3O_2\to 2N_2{O}_3$
Therefore the volume ratio of reactants and products $=2:3:2$
