Homework Help: Chemistry - Rate Determining Step

Posted by Christine on Tuesday, February 6, 2007 at 10:35pm.

The rate law for the reaction
2NO (g) + Cl2 (g) -> 2NOCl (g)
is given by
rate = k[NO][Cl2]
A mechanism involving the following steps has been proposed for the reaction:
NO (g) + Cl2 (g) -> NOCl2 (g)
NOCl2 (g) + NO (g) -> 2NOCl (g)
If this mechanism is correct, what does it imply about the relative rates of these two steps?

I think to solve this I have to find the rate determining step. I first thought the first step was the RDS because it has the right reactants. However, maybe it is the second one because the NOCl2 can be replaced by the NO and Cl2 from the first step and then the coefficients will be the same as in the overall reaction? PLEASE HELP!!!!!
