The answer is microvilli.
They attract because they have opposite charges
<u>Answer:</u> Step 2 in the given mechanism is the rate determining step
<u>Explanation:</u>
In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.
The intermediate reaction of the mechanism follows:
<u>Step 1:</u> 
<u>Step 2:</u> 
As, step 2 is the slow step. It is the rate determining step
Rate law for the reaction follows:
![\text{Rate}=k[O_3][O]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BO_3%5D%5BO%5D)
Hence, step 2 in the given mechanism is the rate determining step
Answer:
nitrogen monoxide: NO
nitrogen dioxide: NO₂
Explanation:
Nitrogen monoxide is composed by 1 atom of O (prefix "mono-") and 1 atom of N. Nitrogen dioxide is composed by 2 atoms of O (prefix "di-") and 1 atom of N. As the oxigen atom in oxides has the valency -2 (it shares 2 electrons), the nitrogen has valency +2 in NO and +4 in NO₂.
