Chlorine atoms from cfc molecules speed the breakdown of stratospheric o3 in a process that is affected by both homogeneous and heterogeneous catalysis.

true or false?

False, just heterogeneous.

Explanation:

Hello,

Ozone layer degradation by the CFC molecules occur in gaseous phase since no liquids or solids are involved at those stratospheric conditions. In addition, that is a chemical reaction undergoing by itself as long as the ozone () is pretty much chemically unstable, so there is no necessity of a catalyst.

Best regards.
