A Possible Reaction Leading to Removal of ClO from the Atmosphere

question 115

Multiple Choice

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.

• A) 1.5 × 10^{-15 M-1} s^-1
• B) 8.7 × 10⁵ M^-1 s^-1
• C) 2.9 × 10^{-15 M-1} s^-1
• D) 9.9 × 10^{-13 M-1} s^-1
• E) 1.7 × 10⁶ M^-1 s^-1
