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]/dr = k[NO₂].x The equations corresponding to the possible orders of the reaction follow: i. zero order: [NO₂] = [NO:]0 - kt ii. first order: In ([NO]0/[NO₂]) = kt iii. second order: 1/[NO₂] = kt + 1/[NO₂]0 Use Excel to determine the order and rate constant of the reaction given the following data: Time (s) 0 10 20 30 40 50 60 [NO₂] (M) 0.100 0.0506 0.0329 0.0253 0.0204 0.0163 0.0143 Note that in this problem you are given the concentration of NO² (in molarity), not the absorbance of a solution of NO₂. You do not need to use the Beer's law relationship between absorbance and concentration to solve this problem. Plot the "best fit" line. Hand in the relevant plots and data tables.
