QUESTION 1 a reaction that has an activation energy of 10.4 kJ/mol. What i constant at -41 0 ons exhibit rates that vary considerably with temperature. This is explored in Box 1-2 of the text. Consider a paral stuation for s the RATIO (not the absolute numbern of the rate constant at-20 °c compared to the rate QUESTION 2 How much energy in kJ/mo will be imparted by photons of wavelength 254 nm? Give the answer in kJ/mol but do not write in this unit, only give the digits, including the first decimal place. 469.1 QUESTION 3 The OH free radical is one of the catalysts which can destroy ozone through Mechanism I. OH is produced by a reaction between excited oxygen and methane which migrates to the stratosphere from the surface of the earth: O. + CH4 = > OH + CH3 This is discussed on page 25 of the text. If you assume that the reaction occurs in one step, the rate of the reaction equals its rate constant times the cancentrations of the two reactants. At a typical temperature the rate constant is 3.0x10 10 cm molecules 1 s 1 Given these concentrations, O 75 and CH4 2.4 x 1011 both in molecules cm 3, how many mg/km3 of methane would be destroyed each minute? The units were selected such that your answer will be a number between 1 and 10 mg/km3
