write the four difference between photochemical reaction and electrochemical reaction
Answers
The key difference between photochemical and electrochemical reaction is that photochemical reactions occur due to the absorption of light energy, whereas electrochemical reactions occur due to the absorption of electric energy.
What is a Photochemical Reaction?
A photochemical reaction is a type of chemical reaction that is initiated by the absorption of energy in the form of light. And, this energy absorption of the molecules leads to the creation of transient excited states whose chemical and physical properties differ greatly from the original state of the molecule. The newly formed chemical species differs from the initial state by changing to new structures (via combining with each other or other molecules, via transferring electrons, hydrogen atoms, protons, etc.
What is Electrochemical Reaction?
An electrochemical reaction is a type of chemical reaction that is accompanied by the passage of an electric current. Mostly, this type of reactions involves the transfer of electrons between two substances (one substance is a solid, and the other substance is a liquid).
Difference Between Photochemical and Electrochemical Reaction
The key difference between photochemical and electrochemical reaction is that photochemical reactions occur due to the absorption of light energy, whereas electrochemical reactions occur due to the absorption of electric energy.
Photochemical reactions and electrochemical reactions are two types of chemical reactions that take place in the presence of two different energy sources. However, both these reactions are often endothermic reactions.
Photochemical and electrochemical reactions are chemical reactions that take place under the influence of two different energy sources. The key difference between photochemical and electrochemical reaction is that photochemical reactions occur due to the absorption of light energy, whereas electrochemical reactions occur due to the absorption of electric energy.
