True and false about elementary reactions

[From: ] [author: ] [Date: 11-04-25] [Hit: ]
one in which three atoms simultaneously collide.1.2.3.......
Seems simple enough, but I can't seem to get them all right. Please help if you can!

The reaction of NO with Cl2 is:
2NO + Cl2 → 2NOCl

The following criteria are given:

1. A unimolecular decomposition that generates Cl
2. A bimolecular collision in which a Cl atom is transferred between initial reactants
3. An intermolecular collision leading to the observed products
Which of the following elementary reactions satisfy the criteria above?

1. 2NO + Cl2 → 2NOCl
2. NO + Cl2 → 2Cl + NO
3. NO + Cl2 → NOCl + Cl
4. NO + Cl → NOCl
5. Cl2 → 2Cl
6. NOCl + Cl → NO + Cl2

Answer in True or False format.

When you study kinetics you learn that the rate equation can't be determined from the overall stoichiometry by the law of mass action. The rate law comes from the stoichiometry of the rate determining step, also known as the "rate-determining step" in the overall mechanism.

In number 3, I think you mean a "termolecular" collision, one in which three atoms simultaneously collide.

1. Cl2 → 2Cl
2. NO + Cl2 → NOCl + Cl
3. 2NO + Cl2 → 2NOCl
