The order of reaction is:

Options:

Answer:

Solution:

$NH_{4} NO_{2} ⟶ N_{2} + 2 H_{2} O$ Volume of $N_{2}$ formed in successive five minutes are $2.75 cc, 2.40 cc$ and $2.25 cc$ which is in decreasing order. So rate of reaction is dependent on concentration of $NH_{4} NO_{2}$ . As decrease is not very fast so it will be first order reaction.
