The concentration of atmospheric methane is 1.8 ppm, and the rate constant for the reaction between CH and OH is 3.6 x 10-15 cm3 molecule-1 s-1. Calculate the rate, in teragrams per year, of methane destruction by reaction with hydroxyl radical, the concentration of which is 8.7 x 105 molecules cm -3. See Problem 5-6 for additional data.
