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 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/(mol 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 E 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

plotting is tough here , however hope this info helps k = Aexp(-E/RT) ln k = ln A -(E/R)(1/T) so plot of ln K vs 1/T gives straight line with slope -E/R and intercept ln A
