Question

Give two examples of gaseous first-order reactions.

Answer 1

The following are the examples of gaseous first-order reactions.
(1) The decomposition of dinitrogen pentoxide $N_2{O}_5$
$2N_2{O}_5\left(g\right)\to 4N{O}_2\left(g\right)+O_2\left(g\right)$
(2) The decomposition of azomethane $C{H}_3{N}_{2}C{H}_3$
$C{H}_3{N}_{2}C{H}_3\left(g\right)\to C{H}_{3}C{H}_3\left(g\right)+N_2\left(g\right)$
