Formation of free radicals: The ionic products which are formed during Radiolysis of Water Vapour are very reactive. So they get recombined to form free radicals. The formation of free…
Water when irradiated with x-rays or γ-rays results into the formation of high energy electrons. These high energy electrons are known as Hydrated Electron. During collisions these electrons lose some…
2 1H1 + 2 0n1 —–>2He4 Check whether the reaction is exoergic or endoergic? The exact mass of 1H1 isotope = 1.0081 a.m.u. and that of 0n1 = 1.0086 a.m.u.…
92U238 ——> 90Th234 + 2He4 + Q The exact mass of 92U238 isotope = 238.1249 a.m.u. and that of 90Th234 = 234.1165 a.m.u. The exact mass of 2He4 = 4.0039…
Photochemistry is the branch of science which deals with chemical reactions, reactions which occurred by the absorption of light waves which are called photons of energy. Only the radiations which…
Today photochemistry has become one of the most powerful research tool. Compounds of different molecules are occurred through various photochemical reactions like CO<sub>2</sub>, NH<sub>3</sub> and methane. Other examples of photochemical…
According to the principle of photochemical activation, only that part of the light which is absorbed by any system can cause photochemical change or reaction. However this is not essential…
According to Lambert-Beer law, when a beam of monochromatic radiation passes through any solution, the intensity of the beam reduces to some amount. Let if I0 is the intensity of…
1. The primary photochemical process may get backtracked due to any reason. 2. The broken molecules may combine with each other resulting in the formation of the original molecule. 3.…
The chemical reactions which take place with energy changes are known as thermochemistry. A thermochemistry deal with energy changes and it is a branch of chemistry. The energy changes occur…
