45.4 \mathrm{~L}

of dinitrogen reacted with

22.7 \mathrm{~L}

of dioxygen and

45.4 \mathrm{~L}

of nitrous oxide was formed. The reaction is given below.

2 \mathrm{~N}_2(\mathrm{g})+\mathrm{O}_2(\mathrm{g}) \longrightarrow 2 \mathrm{~N}_2 \mathrm{O}(\mathrm{g})

Which law is being obeyed in this experiment?

View answer and explanation

Correct option: D

Gay Lussac's law of gaseous volumes

Option D (Gay Lussac's law of gaseous volumes) is correct because the volumes of the reacting gases and the product bear a simple whole-number ratio to each other, which is consistent with Gay-Lussac's Law.
