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:
$2N_2\left(g\right)+O_2\left(g\right)\to 2N_{2}O\left(g\right)$
Which law is being obeyed in this experiment?

• A. Gay Lussac's law of gaseous volumes
• B. Henry's Law
• C. Raoult's Law
• D. None

Answer 1

Answer: (A)

Gay Lussac's law of gaseous volumes

The ratio of the volumes of dinitrogen, oxygen and nitrous oxide is $45.4$ : $22.7$ : $45.4$ . This is in the simple whole number ratio $2:1:2$.
This satisfies the Gay Lussac's law of combining volume of gases.
