How does depend on the concentrations of the reactants and products in the redox reaction occurring in the cell? What effect does increasing the concentration of a reactant have on ? Increasing the concentration of a product?
Answer :Step 1:Photo dissociationOne type of photochemical reaction is the dissociation of a molecule into two fragments. Since itis the electrons that provide the bonding forces that hold atoms together into molecules, if thedistribution of electrons within a molecule changes drastically, the bonding forces may alsochange. In photodissociation, also called photolysis, the absorption of light raises the moleculeinto an excited state in which one of the chemical bonds no longer exists. Thus, absorption oflight causes cleavage of a chemical bond and the release of two fragments called radicalsbecause they each have enough electrons to form half of a chemical bond and are generally quitereactive.
