The answer is D. To put it simply, all atom wished to become stable. The only way for that is to obtain an octet structure where the outermost shell would have 8 electrons, thus being full.

The decomposition reaction 2 NOCl → 2 NO + Cl_2 has a rate law that is second order with respect to [NOCl], where k = 3.2 M^{-1

SashulF [63]

Answer:

It will take 3.3 s for [NOCl] to decrease to 0.042 M.

Explanation:

Integrated rate law for this second order reaction-

$\frac{1}{[NOCl]}=kt+\frac{1}{[NOCl]_{0}}$

where, [NOCl] is concentration of NOCl after "t" time, $[NOCl]_{0}$ is initial concentration of NOCl and k is rate constant.

Here, $[NOCl]_{0}$ = 0.076 M, k = 3.2 $M^{-1}s^{-1}$ and [NOCl] = 0.042 M

So, $\frac{1}{0.042M}=[3.2M^{-1}s^{-1}\times t]+\frac{1}{0.076M}$

or, t = 3.3 s

So, it will take 3.3 s for [NOCl] to decrease to 0.042 M.
