EXAM 1 PROBLEMS I. Chlorine atoms react rapidly with ozone in the gas-phase bimolecular reaction Cl + O 3 --> ClO + O 2 with k = 1.7 × 10 10 exp { } M −1 s −1 At 20 km: [Cl] 0 = 5 × 10 −17 M [O 3 ] 0 = 8 × 10 −9 M T = 220 K a) What is the value of the activation energy in kJ per mole? Note: R = 8.3145 J K -1 mol -1 . b) What is the value of the rate constant at 20 km when T = 220 K? c) Estimate [ClO] after 10 s.
