From: | To: |
Definition: This calculator estimates the energy absorbed by one mole of a substance undergoing a photochemical reaction based on the frequency of light.
Purpose: It helps chemists and researchers determine the energy requirements for photochemical processes.
The calculator uses the formula:
Where:
Explanation: The energy is calculated by multiplying Avogadro's number, Planck's constant, and the frequency of the light.
Details: Accurate energy calculation helps in understanding reaction mechanisms, predicting reaction rates, and designing efficient photochemical processes.
Tips: Enter the frequency of light in Hertz (Hz). The value must be greater than 0.
Q1: What is Avogadro's number?
A: It's the number of particles (atoms or molecules) in one mole of a substance (6.02214076×10²³ mol⁻¹).
Q2: What is Planck's constant?
A: It's a fundamental constant (6.626070040×10⁻³⁴ J·s) that relates the energy of a photon to its frequency.
Q3: How do I find the frequency of light?
A: Frequency can be calculated from wavelength using \( f = c/\lambda \), where c is the speed of light.
Q4: What units does this calculator use?
A: The calculator uses SI units - Hertz (Hz) for frequency and Joules (J) for energy.
Q5: Can I use this for non-photochemical reactions?
A: This specifically calculates energy for photochemical reactions where light is absorbed.
