Question 1

in CFC’s what bond is broken and how

Answer 1

in CFC’s the C- Cl is broken by UV light due to there being a lot of UV in the atmosphere

Question 2

what is produced when the C-Cl bond in CFC’s is broken

Answer 2

a chlorine free radical

Question 3

what does the chlorine free radical do

Answer 3

acts as a catalyst in the destruction of the ozone layer

Question 4

identify the radical produced from CFC’s that are responsible for the depletion of the ozone in the atmosphere

explain with equations, why a single radical can cause the decomposition of many molecules of ozone

Answer 4

chlorine

. .
Cl + O3 —> ClO + O2

.                    . ClO + O3 ---> Cl + 2O2

Cl is regenerated and causes a chain reaction in the decomposition of ozone
