A Possible Reaction Leading to Removal of ClO from the Atmosphere

question 13

Multiple Choice

A possible reaction leading to removal of ClO from the atmosphere is 2ClO $\rarr$ Cl₂ + O₂. Studies of this reaction have yielded an Arrhenius frequency factor (A) and 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 ^$\circ$ 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
