Question

which of the following are the principle laws of photochemistry:- 1.gorthus- dorper and stark enstin low. 2.roult's law and Dalton's law. 3. roults and Henry law. 4.lamberts and beers law.​

Answer 1

Answer:

It follows two basics laws that his Grotthuss-Draper law and Stark-Einsten law.

Hope it helps.

Answer 2

OPTION 1. IS CORRECT.

1. GORTHUS-DOPER AND STARK EINSTEIN LAW.

Explanation:

• The photochemistry involves the chemical reactions that occur due to absorption of UV, visible, and IR radiations.
• There exist 2 laws of photochemistry which are:

1. Grothus-Draper Law
2. Stark-Einstein Law

• The grothus draper law states that chemical reactions occur by the radiations absorbed by the object. Not all absorptions cause chemical reactions, some can cause thermal transformations, fluorescence, etc.
• The Stark-Einstein Law states that one quantum of radiation is absorbed by each atom/molecule taking part in chemical reactions.
