CALCULATIONS
 

Overall Concentration (ambient pressure 1 atm, ambient temperature 298 K):

    [M] = (n . NA) / V = (p . NA) / RT
    [M] = (101325 . NA / (8.314 . 298)
    [M] = 2.46 x 1019 molecules / cm3

Oxygen Concentration (5% O2)

    [O2] = 2.46 x 1019  x 0.05 = 1.23 x 1018 molecules / cm3

Calculation of Rate Constant k1

      k1 = (k' / [O2]) / [M]

      k' / [O2]  = m    (Slope of Figure 3)

      k1 = m / [M]

      k1  = 1.18 x10-14 / 2.46 x 1019

      k1 = (5.0 + 1.2) x 10-34 cm6 molecule-2 sec-1
