Question

What are photosensitised chemical reactions? Explain giving suitable examples.

Answer 1

those chemical reactions takes place in photosynthesis is called photosensitised chemical reaction.
ex ATP form in plants.

Answer 2

Explanation:

Is the process in which light energy is absorbed by the reactants absorbed molecules to initiate the reaction.These reaction also occurs in cell of the living organism. For example:

Photodecomposition of ethylene to acetylene and hydrgen.

$CH_2=CH_2\overset{h\nu}\rightarrow CH\equiv CH+H_2$

Molecule which absorbs the light is knows as photosensetizer. The molecule which receives energy from the photosensitive is called substrate or acceptor.
