QUESTION 2 At 298 K the Arrhenius parameters for the reaction .OH + H2 --> H2O + .H are A = 8.1 x 1010 s-1 and Ea = 44 kJ/mol. If the concentration of hydroxyl radical in the atmosphere is 7.3 x 105 molecules cm-3 and the concentration of hydrogen is 496 ppbv calculate the rate of the reaction in units of molecules cm-3 s-1. R= 8.314 J/mol.K. The units indicate this is a psuedo first-order reaction. Give your answer in scientific notation to one decimal place. Do not include units in your answer. If your answer is, for example, 1,521 molecules cm-3 s-1 you would enter 1.5E3 or 1.5e3 with no spaces.
