photosensitization

There are many reactions, where in the reactants undergo transformation not by direct absorption of photons but via the process of photosensitization. In such reactions, a photosensitive substance is added which actually absorbs the photon. The absorbed energy is then pass..

In photosynthesis, chlorophyll present in the chloroplasts acts as a photosensitizer. Light is absorbed by chlorophyll and then this energy is used to split the water molecule into molecular oxygen and hydrogen equivalent. In the process, nicotinamide adenine dinucelotide phosphate ..

Photosynthesis - Example 22: In photosynthesis, chlorophyll present in the chloroplasts acts as a photosensitizer. Light is absorbed by chlorophyll and then this energy is used to split the water molecule into molecular oxygen and hydrogen equivalent. In the process, nicotinamide adenine ..

Photocells and their Application..

Solar Cells - Solar cells are expensive and are used only when supplying electricity becomes difficult. Solar cells are the devices where solar energy is directly converted into electricity. Solar cells are used in spacecrafts, radios, television, refrigerators, buoys and other navigation aid. Sola..

. This is the rate determining step of the complex reaction. A catalyst is substance that accelerates a reaction but does not take part in the reaction. Catalyst enhances the rate of reaction by lowering the activation energy of the reaction. Photochemical reactions are induced by the absorption of..
