A possible reaction leading to removal of ClO from the atmosphere is 2ClO → Cl2 + O2.Studies of this reaction have yielded an Arrhenius frequency factor,A,and an activation energy of 1.0 × 10-12 cm3 molecule-1 s-1 and 13.2 kJ/mol,respectively.Calculate the rate constant for the disappearance of ClO at -30°C.
