Data Analysis:
Hand in three plots (zero, first and second order) and the Excel worksheet of your data and
results.
Is the reaction zero, first or second order with respect to dichromate?
What is the value of the rate constant? What are the units? Use the value 3.58 x 102 M¹ for
el, if necessary.
Thermal decomposition of nitrogen dioxide to nitric oxide and oxygen occurs according to
the following reaction:
The rate law is:
2 NO₂+2 NO + O₂
-d[NO₂]/dt
= /[NO₂].x
The equations corresponding to the possible orders of the reaction follow:
i. zero order: [NO₂] = [NO₂]0 - kt
ii. first order: In([NO₂]0/[NO₂]) = kt
