Question

Which of the following free radicals is responsible for causing break down of ozone into oxygen due to use of $ CFCs $ ?

• A. $ \frac{-1}{e} $
• B. $ \frac{1}{e} $
• C. $ lx+my=1 $
• D. $ {{x}^{2}}+{{y}^{2}}={{a}^{2}} $

Answer 1

Answer: (B)

$ E_{cell}^{o}=\frac{0.059}{2}\log {{k}_{c}}=11V $ $ \log {{k}_{c}}=\frac{1.1v\times 2}{0.059v}=37.288 $ $ {{k}_{c}}=2\times {{10}^{37}}at\,298k $ The chlorine radicals are continuously regenerated and cause the breakdown of ozone.
