The following reaction is the main mechanism for the removal of NO2 from the atmosphere: NO2 + OH + M   → HNO3 + M The rate constant for this reaction is 4.80×10-31×(T/298 K)-1.6 cm6 molecule-2 s-1. (T is the temperature in K.) Determine the lifetime (in hours) of NO2 with regard to this reaction, assuming a temperature of 25.7°C, a pressure of 0.913 atm, and an OH concentration of 2×106 molecule cm-3.
