Question

So far I was able to complete the info of this chart. I dont really know where to go from here.

Please show all work.

(In Class. OPTIONAL) A pseudo first-order kinetics experiment was earned out using the same method as described above. The reaction was first run with [Hz]e = 0.0450 M and (NO]e = 4.00 M. The reaction was then run with [Hz]e = 0.0450 M and [NO]e = 2.00 M. The time and concentration data are given in the table. Determine the complete rate law for this reaction by using Excel to graph the data according to the pseudo first order method, and using the resets from the graphs to determine m, n and k tor the reaction.

Explanation / Answer

you have done almost all the calculations

As its a pseudo first order rxn rate r=-d[H2]/dt is the rate of reaction , you can easily make a column in excel for rate as time changes , r=-d[H2]/dt=k[NO][H2]^n =K[H2]^n where K=k[NO] as its pseudo first order

Now plot log of rate versus log of [H2] in excel which will be straight line

because log r = logK + nlog[H2] , by curvr fitting you can get the equation of the line so from there you can get n and K ( from K you can get k) , i think thats all you need

I hope you can work out those easy calculations in excel , if not let me know :)
