Energy of Photochemical Reaction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Energy in Photochemical Reaction = [Avaga-no]*[hP]*Frequency
E = [Avaga-no]*[hP]*f
This formula uses 2 Constants, 2 Variables

Constants Used

[Avaga-no] - Avogadro’s number Value Taken As 6.02214076E+23
[hP] - Planck constant Value Taken As 6.626070040E-34

Variables Used

Energy in Photochemical Reaction - (Measured in Joule) - Energy in photochemical reaction is the energy absorbed by one mole of a substance which is undergoing a photochemical reaction.
Frequency - (Measured in Hertz) - Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second.

STEP 1: Convert Input(s) to Base Unit

Frequency: 90 Hertz --> 90 Hertz No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = [Avaga-no]*[hP]*f --> [Avaga-no]*[hP]*90

Evaluating ... ...

E = 3.59128138198489E-08

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.
