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.
