What specific name can be given to the following sequence of steps:
`Hg+hv rarr Hg^(**)`
`Hg^(**) + H_(2) rarr H_(2)^(**)+Hg`

A

Photosensitization

B

Phosphorescence

C

Fluorescence

D

Chemiluminescence

Text Solution

Verified by Experts

The correct Answer is:
a
The phenomenon in which a foreign material (here Hg) absorbs photon and then passes it to other reactant species (incapable of absorbing photon, here `H_(2)`) to show chemical changes is called photosensitisation.
