A possible reaction leading to removal of ClO from the atmosphere is 2ClO=Cl2+O2

Question

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 1.0x10^-12 cm molecule-1s-1 and 13.2 kj/mol respectively. Calculate the rate constant for the disappearance of ClO at -30c. A possible reaction leading to removal of ClO from the atmosphere is 2ClO=Cl2+O2.

Calculate the rate constant for the disappearance of ClO at -30c.

Explanation / Answer

arrhenius equation..
k = A x exp(-Ea/(RT))

=1.0x10^-14 m molecule-1s-1 * exp(-13200 j/mol / (8.314*243))

k = 1.453*10-17 m molecule-1s-1
