The following data are obtained for the decomposition of N2O5 at a certain temperature:

2N2O5(g)↔4NO2(g) + O2(g)

Time(s) 0 200 400 600 800
N2O5 (atm) 2.10 1.85 1.63 1.43 1.26

Find the rate constant kobs for this first-order decomposition reaction in sec-1

So far I have two equations that I think are needed: ln([At]/[Ao])=-kt and PV=nRT but how to proceed?

I believe you need to plot the data and determine the slope of the straight line. Plot ln A vs time.

But A stands for concentration..how would i obtain it from the data given?
