Title: 4th Order Kinetics?
Post by: mollyp on November 13, 2008, 11:42:49 PM

If a reaction is found to be 4th order, how do i find the slope of the integrated rate law? 

The reaction is the decomposition of NO₂ --> O₂ + NO 

So I have my rate law as:  rate = k [NO₂]⁴

I know that since it is 4th order, it took 4 separate reactions to get to this final reaction and that the slope will get smaller with each reaction.
So do I just integrate it as if it were a 1st order?

Thank you!
