The Reaction of Hydroperoxyl Radical with Ozone, HO₂ (G) $\degree$ OH(g) +2 O₂(g), Is Rapid

question 128

Essay

The reaction of hydroperoxyl radical with ozone, HO₂ (g) + O₃(g) $\degree$ OH(g) +2 O₂(g), is rapid.The rate of reaction is measured in milliseconds for different HO₂ concentrations in the presence of a large excess of O₃. A plot of ln[HO₂] versus time has a slope of -0.0103 and an intercept of -12.991.What is the pseudo-first-order rate constant, and what is the second-order rate constant?
