A Possible Reaction Leading to Removal of ClO from the Atmosphere

question 27

Multiple Choice

A possible reaction leading to removal of ClO from the atmosphere is 2ClO $\to$ Cl₂ + O₂.Studies of this reaction have yielded an Arrhenius frequency factor, A, and an activation energy of 1.0 $\times$ 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.
