Question

45.4 L of dinitrogen reacted with 22.7 L of dioxygen and 45.4 L of nitrous oxide was formed. The reaction is given below:

\[\ce{2N2(g) + O2(g) -> 2N2O(g)}\]

Which law is being obeyed in this experiment? Write the statement of the law?

Answer 1

If all gases are at the same temperature and pressure, Gay lussac's law of gaseous volumes states that gases combine or are created in a chemical reaction in a simple volume ratio.

\[\ce{H2(g) + Cl2(g) -> 2HCl(g)}\]

1 volume : 1 volume : 2 voulme

22.4 litre : 22.4 litre : 44.8 litre

\[\ce{2N2(g) + O2(g) -> 2NO(g)}\]

2Vol : 1Vol : 2Vol

45.4 litre : 22.7 litre : 45.4 litre

2 : 1 : 2

The above examples proved that gaseous volumes combine in a simple volume ratio.
