The degradation of cf3ch2f (an hfc) by oh radicals in the troposphere is first order in each reactant and has a rate constant of k = 1.6 x 10^8 m^-1s^-1 at 4°c.
part a) if the tropospheric concentrations of oh and cf3ch2f are 8.1 x 10^5 and 6.3 x 10^8 molecules/cm^3, respectively, what is the rate of reaction at this temperature in m/s?
