In unpolluted air at 300 K, the hydroxyl radical OH reacts with CO with a bimolecular rate constant of 1.6 × 101' L mol-1 s-1 and with CH4 with a rate constant of 3.8 × 10° L mol¬1 s-1. Take the partial pressure of CO in air to be constant at 1.0 × 10-7 atm and that of CH4 to be 1.7 x 10-6 atm, and assume that these are the primary mecha- nisms by which OH is consumed in the atmosphere. Cal- culate the half-life of OH under these conditions.
