I'm stuck on this question...

The following first order rate constants for the gas phase decomposition of N2O5 have been obtained as a function of number density at 298k.

kobs/10-3s-1    7.81  12.5 15.6
[M]/mol m-3     10      25    50

Show these data are consistant with the lindemann mechanism and derive a rate constant and a ratio of two rate constants for elementary reactions in the mechanism. What are the units of the two quantities.


To show the data was consistant with the lindemann mechanism, i just plotted a graph of 1/k vs 1/[M]  but im unsure of how to go about deriving a rate constant and ratio of rate constants.
