At 300 K, the following reaction is found to obey the rate law of Rate = k[NOCl]^2:

2 NOCl(g)  2 NO(g) + Cl2(g)

The following reaction mechanism has been proposed for the reaction above:

Proposed Mechanism: NOCl(g) ->NO(g) + Cl(g) slow

Cl(g) + NOCl(g) -> NOCl(g) fast

NOCl2(g) -> NO(g) + Cl2(g) fast

21. The suggested rate law in the mechanism is Rate = k[NOCl]. (T)

22. The reaction mechanism is plausible. (F)

23. NOCl2 is a catalyst in the proposed mechanism. (F)

24. The units for k would be M−1s−1. (T)

25. The sum of the elementary steps does equal the overall reaction. (T)

26. The molecularity of one of the steps describes the simultaneous collision of more than three particles. (F)

Please explain why 21-26 are True or False. The answers next to each question are correct
