3) Methane (CH4) is a potent greenhouse gas. In the atmosphere, it reacts with hydroxyl radical (OH:) according to the elementary reaction shown below. CH4 + OH: → 3CH3 + H>O The rate constant for the reaction has been reported to be 2.4 x 10-15 cm³ molecule1 s 1 (at 20°C). During the daytime, OH: is maintained by photochemical reactions at a constant value of 1.7 x 109 moles per liter. Calculate the time it takes for CH4 to be reduced by 99% under these conditions
