During photochemical reaction between K3[Fe(C2O4)3]3H20 (Ferric Potassium Oxalate) and K3Fe(CN)6, I had to Sulfuric Acid. What is the reason Sulfuric acid must be added?
It acts as a catalyst.

Photochemical Reaction $70.1 High Quality Content by WIKIPEDIA articles In the area of photochemistry, a photochemical reaction is a chemical reaction that is induced by light. Photochemical reactions are valuable in organic and inorganic chemistry because they proceed differently than thermal reactions. Photochemical reactions are not only very useful but also can be a serious nuiscance, as in the photodegradation of many materials, e.g. polyvinyl chloride. A largescale application of photochemistry is photoresist technology, used in the production of microelectronic components. Vision is initiated by a photochemical reaction of rhodopsin. Photochemical reactions require a light source that emits wavelengths corresponding to an electronic transition in the reactant. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Photochemical Kinetics by Saeed, Rehana [Paperback] $151.35 Before the development of a theoretical background and extensive support of the experimental data photochemistry was thought to be a flimsy subject, devoid of system with a number of processes involved and ill equipped with apparatus but the dawn of quantum mechanics and kinetics elucidate a vast field of research and since then photochemistry has played a vital role in chemistry. Thiazine dyes provide a vast field for the studies of photochemical kinetics in the presence of reductant. Methylene green is a member of thiazine dye which undergoes reduction by the visible light with reductant in presence of buffer solution. Acidity plays a significant role in the reduction of dye. The quantum yield for photochemical reduction used to study the kinetics of reaction which helps to propose reaction mechanism. The triplet excited state of methylene green played a major contribution for the determination of quantum yield. An equilibrium was established between associated complex and one form of triplet state of methylene green with reductant and the complex is the rate controlling specie.

Substitution Reaction $70.1 High Quality Content by WIKIPEDIA articles In a substitution reaction, a functional group in a particular chemical compound is replaced by another group. In organic chemistry, the electrophilic and nucleophilic substitution reactions are of prime importance. Organic substitution reactions are classified in several main organic reaction types depending on whether the reagent that brings about the substitution is considered an electrophile or a nucleophile, whether a reactive intermediate involved in the reaction is a carbocation, a carbanion or a free radical or whether the substrate is aliphatic or aromatic. Detailed understanding of a reaction type helps to predict the product outcome in a reaction. It also is helpful for optimizing a reaction with regard to variables such as temperature and choice of solvent. A good example of a substitution reaction is the photochemical chlorination of methane forming methyl chlorid. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

The Double [3+2] Photocycloaddition Reaction (Hardcover) $259.42 Jason Woolford`s thesis describes for the first time, a double [3+2] photocycloaddition of alkenes onto aromatic rings. Modern synthetic chemistry relies on the ability of researchers to uncover new and more efficient ways of creating highly complex structures. This work describes a novel, environmentally friendly photochemical step that converts in one pot, trivial starting materials into otherwise difficult to construct fenstrane frameworks. The rigid cores of these frameworks have significant potential in drug design. Moreover, the novelty of this work overtakes many other methods for the creation of chiral centres. No less than seven chiral centres are created in the photochemical step together with the formation of four carbon-carbon bonds and multifused rings. Jason`s innovative work has been the subject of several publications in peer-reviewed journals. |

Activation energy
physics question?!?
Q: a still camera works by having a shutter that opens briefly to allow light to pass through an aperture. when light passes through this aperture, film in the camera is exposed to light and the image is then burned onto the film in a photochemical reaction. anyone who has every tried to photograph of a fast moving object like a runner will notice that often on the developed photograph, the legs of the runner seem blurred
(a) what does this say about instantaneous speed of the runner's legs and why the picture is blurred ( hint: think about the shutter speed of a camera and how fast the runner's legs are moving at the instant the picture is taken)
(b) as a photographer, what would you do to get a clearer picture of the fast moving runner next time?
speed of legs is fast enough to move considerably within the time range of the shutter, thus you get images of the legs at various positions entering the shutter
make the shutter open/close faster, or make the runner run slower
