Answer:
C.
Explanation:
We are given that
Initial concentration, ![[A]_o=4.3 M](https://tex.z-dn.net/?f=%5BA%5D_o%3D4.3%20M)
First half life,
minutes
Second half life,
minutes
We have to find K.
The given reaction is zero order reaction.
We know that for zero order reaction
![t_{\frac{1}{2}}=\frac{[A]_o}{2k}](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cfrac%7B%5BA%5D_o%7D%7B2k%7D)
Using the formula



Hence, option C is correct.
High pressure system circulate clockwise.low is counter clock wise circulation going upward.
The right answer is indeed letter c
