345249
Which of the following acts as catalyst in Ozone depletion in stratosphere?
1 \(\mathrm{Cl}_{2}\) molecule
2 \(\mathrm{C}_{6}\) molecule
3 C atom
4 \(\mathrm{Cl}\) atom.
Explanation:
\(\mathrm{Cl}\) atom acts as catalyst during Ozone depletion.

\(\mathrm{Cl}\) atoms added to the stratosphere by \(\mathrm{CFCs}\) have
1 Permanent and continuous effect on \(\mathrm{SO}_{2}\) levels.
2 Temporary and discontinuous effect in \(\mathrm{H}_{2}\) levels.
3 Temporary and continuing effects on Ozone levels.
4 Permanent and continuing effects on Ozone levels.
Explanation:
\(\mathrm{Cl}\) atoms added by CFCs to the stratosphere, have permanent and continuing effects on Ozone levels, because \(\mathrm{Cl}\) atoms are not consumed in the ozone degradation reaction as they act as catalyst.

In stratosphere, which of the following elements acts as a catalyst in degradation of ozone and release of molecular oxygen?
1 \(\mathrm{Fe}\)
2 \(\mathrm{Cl}\)
3 Carbon
4 Oxygen
Explanation:
UV rays acts on Chlorofluoro carbon \({\rm{(CFC)}}\) release chlorine, which acts with ozone in sequential method converting into oxygen.
