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}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5BNOCl%5D%7D%3Dkt%2B%5Cfrac%7B1%7D%7B%5BNOCl%5D_%7B0%7D%7D)
where, [NOCl] is concentration of NOCl after "t" time, ![[NOCl]_{0}](https://tex.z-dn.net/?f=%5BNOCl%5D_%7B0%7D)
is initial concentration of NOCl and k is rate constant.
Here, = 0.076 M, k = 3.2 
and [NOCl] = 0.042 M
So, ![\frac{1}{0.042M}=[3.2M^{-1}s^{-1}\times t]+\frac{1}{0.076M}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B0.042M%7D%3D%5B3.2M%5E%7B-1%7Ds%5E%7B-1%7D%5Ctimes%20t%5D%2B%5Cfrac%7B1%7D%7B0.076M%7D)
or, t = 3.3 s
So, it will take 3.3 s for [NOCl] to decrease to 0.042 M.
A reaction in which two ions switch places is called double-displacement reaction.
Explanation:
Double displacement reaction usually takes place between two positive ions or two negative ions. When anions or cations of totally different compounds change places, two totally different compounds are formed.
<u>Syntax for double displacement reaction:
</u>
AB + CD --> AD + BC
It can also be defined in simple terms as the reaction in which exchange of ions takes place is called double displacement reaction.
The chemical reaction is as follows:
NaOH(aq) + HCl(aq) --> NaCl(aq) + H2O (l)
