What is Stark-Einstein law of photochemical equivalence?

Stark-Einstein law of photochemical equivalence can be stated as follows: Each molecule taking part in a photochemical reaction absorbs one quantum of radiation which causes the reaction. This law is applicable to the primary act of excitation of a molecule by light absorption. This law helps in calculating the quantum efficiency which is a measure of the efficiency of the use of light in a photochemical reaction.

What is Grotthuss-Draper Law?

According to this law, only the light that is absorbed by a molecule can produce a photochemical change in it. This means that it is not sufficient to pass light through a substance to bring about a chemical reaction; but the light must be absorbed by it. Stark-Einstein law of photochemical equivalence provides a quantum mechanical form to Grotthuss-Draper law.
