Can answer the second question...

Data for the rate of decomposition of nitrogen dioxide as a function of temperature are given in the table below. Such rate data are expected to follow the Arrhenius equation k = Ae-E/RT where A is the pre-exponential factor, E is the activation energy, T is the temperature in Kelvin, and R is the gas constant, given by R= 1.987 cal/fmol K). Assuming that this data follows the Arrhenius equation, explain how you would plot it to give a straight line. Plot the data in the manner described in part 1 and find A and B from the resulting straight line (plot the data using the grid layout on your engineering paper). Be sure to include the proper units for each of these parameters.

Explanation / Answer

k=Aexp{-E_a/RT} ln k= ln A-{E_a/RT} Now if you try to plot ln k vs 1/T , you get a straight line with Negative slope (-E_a/RT) and positive y-intercept of ln A. You can easily figure out A(Arhenius constant) as well as Activation Energy (E_a) using the table
