The decomposition of nitrogen dioxide to nitrogen monoxide and oxygen gas is a second order process as suspected in the previous

lesya [120]

Explanation:

For the given reaction $2NO_{2} \rightarrow 2NO + O_{2}$

Now, expression for half-life of a second order reaction is as follows.

$t_{1/2} = \frac{1}{[A_{0}]k}$ ....... (1)

Second half life of this reaction will be $t_{1/4}$ . So, expression for this will be as follows.

$t_{1/4}$ = $\frac{1}{k} [\frac{1}{[A]_{f}} - \frac{1}{[A_{0}]}]$ ...(2)

where $[A]_{f}$ is the final concentration that is, $\frac{[A]_{0}}{4}$ here and $[A]_{i}$ is the initial concentration.

Hence, putting these values into equation (2) formula as follows.

$t_{1/4}$ = $\frac{1}{k} [\frac{4}{[A]_{0}} - \frac{1}{[A_{0}]}]$

= $\frac{3}{[A_{0}]k}$ ...... (3)

Now, dividing equation (3) by equation (1) as follows.

$\frac{t_{1/4}}{t_{1/2}}$ = $\frac{3}{[A_{0}]k} \times [A_{0}]k$

= 3

or, $t_{1/4}$ = 3 $t_{1/2}$

Thus, we can conclude that one would expect the second half-life of this reaction to be three times the first half-life of this reaction.
