What chem reactn gives the highest rate of photons emssn/t ?

In summary, there are various chemical reactions that emit light, such as magnesium combustion and the thermite reaction. This light is produced through incandescence or electronically excited molecules/atoms. Some examples include the blue flames of gas stoves, UV light emission from hydrogen-oxygen flames, and the light emission in the abdomen of fireflies. Additionally, chemical lasers such as the HF and COIL can also produce a significant amount of light through chemical reactions.

I was trying to google it, but coudn't find any specific answer. Oxidation of Magnesium, for example, emits a lot of light. Is there a table of reactions by high much light they create ?

What chemical reaction emits the highest number of photons per unit per time ? Thank you.

There are all sorts of chemical reactions that emit photons. I believe that in things like magnesium combustion, the thermite reaction, etc. the light is coming from incandescence -- essentially really hot metals glowing. Some reactions emit light, kind of as a side product, when electronically excited molecules/atoms are produced -- flames are an example of this -- the blue flames of gas stoves coming from electronically excited C2 and CH molecules being produced in the mix. Hydrogen-oxygen flames don't give off much visible light, but produce a lot of UV light emission from electronically excited OH molecules emitting light. The chemical reaction in the abdomen of fireflies is another example of photons being produced in a chemical reaction.

Chemical lasers can emit a great deal of their stored chemical potential energy as photons. The HF laser produces infrared emission when hydrogen and fluorine gases react in a resonator cavity.http://en.wikipedia.org/wiki/Hydrogen_fluoride_laser

The US Air Force is working on a chemical laser: COIL (Chemical Oxygen Iodine Laser) which involves lasing on a transition in Iodine. http://en.wikipedia.org/wiki/Chemical_oxygen_iodine_laser

What is the highest rate of photon emission in a chemical reaction?

The highest rate of photon emission in a chemical reaction is determined by the energy of the reactants and the activation energy required for the reaction to occur. Generally, reactions involving highly energetic reactants and low activation energy will result in a higher rate of photon emission.

How is the rate of photon emission affected by temperature?

As temperature increases, so does the kinetic energy of the reactants. This leads to more frequent and energetic collisions between particles, resulting in a higher rate of photon emission.

Which type of chemical reaction typically gives the highest rate of photon emission?

Oxidation-reduction (redox) reactions, such as combustion, often result in the highest rates of photon emission. This is because these reactions involve the transfer of electrons, which can release a large amount of energy in the form of photons.

Can the concentration of reactants affect the rate of photon emission?

Yes, the concentration of reactants can affect the rate of photon emission. Higher concentrations of reactants can lead to more frequent collisions and a higher rate of photon emission, as long as the activation energy is met.

Is the rate of photon emission constant throughout a chemical reaction?

No, the rate of photon emission can change throughout a chemical reaction. As reactants are consumed and products are formed, the rate of photon emission may decrease due to the decrease in available energy. Additionally, some reactions may have multiple steps with different rates of photon emission.
