Use transition state theory to estimate the pre-exponential factor for the elementary reaction. NO + O2* NO2 + O* Assume T = 528 K. The * represents a catalytic surface. Both O2* and O* are strongly adsorbed species, so they are not mobile. Use orders of magnitude for your estimate. Experimentally it has been found that at 528 K the reaction rate constant for this reaction is 6.9 (2.1) X 103. Compare the value you calculated with the experimental one and explain why the differences are due, if any.
