  1. CH 14 #98 2 N2O5 4 NO2 + O2 RATE= k [N2O5] = 1.0 * 10-5 /S 20 hr = 7.20 * 104 s, [N2O5] = 0.600 ln[A]t – ln[A]0 = -kt ln[A]t – ln[A]0 = -kt ln[N2O5]t =-kt + ln[N2O5]0 ln[N2O5]t = -1.0 * 10-5 (7.2*104 s) + ln(0.600) = -1.231 ln[N2O5]t = e-1.231=0.292 M

  2. 2 N2O5 4 NO2 + O2 Final concentration (0.292) – initial (0.600) = 0.308 mol Use PV=nRT to convert moles of oxygen to P. it is 0.402 atm
