The reaction AgBr → Ag + Br2 is primarily driven by light energy, which facilitates the transition to excited state dynamics necessary for the reaction to occur. While light significantly accelerates this process, it is not the sole energy source capable of inducing the reaction; theoretically, other forms of energy could achieve this, but the energy scale required makes it impractical. Understanding the role of excited state dynamics is crucial for comprehending why light is essential in this reaction.
PREREQUISITESChemists, students of physical chemistry, and researchers interested in photochemical reactions and energy dynamics in chemical processes.
Because it involves excited state dynamics. Heat and other forms of energy deals with ground state dynamics (it is theoretically possible to produce excited states with any form of energy, but it is realistically impossible due to the scale of energy required).shihab-kol said:AgBr →Ag + Br2
This reaction takes place in presence of light energy, but why only light ?? Why not electricity, heat or any other forms of energy?
