Question
State Gay Lussac’s law of combining volumes. Illustrate with suitable examples.
Solution
Gay Lussac’s law (Gay-Lussac’s 1908) states that gases react with each other in the simple ratio of their volumes and if the product is also in gaseous state, the volume of the product also bears a simple ratio with the volumes of the gaseous reactants. The measurement of all the volumes are made under similar conditions of temperature and pressure.

The volume ratio in the above examples is a simple whole number ratio.
