Title: Rate Constant of the Overall Net Reaction
Post by: big on October 20, 2010, 03:51:24 PM

The reaction of ozone with oxygen atoms in the presence of chlorine atoms can occur by the two-step process shown here with the rate constant for each step.

O₃(g) + Cl(g) :rarrow: O₂(g) + ClO(g) k₁=5.2*10⁹
ClO(g) + O(g) :rarrow: Cl(g) + O₂(g) k₂=2.6*10¹⁰

What is the value of the rate constant of the overall net reaction? Shouldn’t it be k₁*k₂=1.4*10²⁰?
