The half-life period for catalytic decomposition of ${AB}_{3}$ at 50 mm is found to be 4 hrs and at 100 mm it is 2 hrs. The order of the reaction is:

Options:

Answer:

Solution:

$t_{\frac{1}{2}} \propto a^{1 - n}$
$\frac{t_{1}}{t_{2}} = {(\frac{a_{1}}{a_{2}})}^{1 - n}$
$\frac{4}{2} = {[\frac{50}{100}]}^{1 - n}$
n= 2

Therefore,the order of reaction is 2.
