At 300 K, half life of a gaseous reactant initially at 58 KPa is 320 min. When the pressure is 29 KPa, the half life is 160 mm. The order of the reaction is

Options:

Answer:

Solution:

$t_{1 / 2} \propto \frac{1}{a^{n - 1}}$
$\frac{t_{2}}{t_{1}} = {(\frac{a_{1}}{a_{2}})}^{n - 1}$
$\frac{160}{320} = {(\frac{58}{29})}^{n - 1}$
n = 0.
