what is mean by photo chemical decomposition
Answers
Answer:
Photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules’ absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules. These new chemical species can fall apart, change to new structures, combine with each other or other molecules, or transfer electrons, hydrogen atoms, protons, or their electronic excitation energy to other molecules. Excited states are stronger acids and stronger reductants than the original ground states.
➡️ Those reactions in which a compound split up into two or more simpler substances are called as decomposition reaction. They are carried out by applying heat,light,electricity. For Ex: ... When decomposition reaction is carried out by light it is called Photochemical decomposition.
