stability product & half life in a chemical reaction

trans-2-Butene cis-2-butene In the hydrogenation of cis- and trans-2-butene, both alkenes react with hydrogen to give the same product, butane. Since cis-2-butene is less stable than trans-2-butene by 0.66 kcal/mol, the energy diagram shows the cis alkene at a higher energy level. After r..

Developing varieties of wider adaptability will help stabilize crop production under unfavourable environmental condition..

Crop yields remaining stagnant, pesticides polluting the eco-systems, increasing cost of fertilizers, reducing soil fertility, imbalance in host - parasite and predator - parasite relationships have pushed agriculture into dangerous mode. Scientists have looked back into the technologies evolved an..

Hybridization is mainly utilized to evolve new hybrids having beneficial heterosis improve / incorporate a specific desirable character so that such progenies are used in further breeding process and desirable improvement can be brought in the concerned crop. A commercial hybrid is a hybrid, where ..

In 1913, Neils Bohr proposed a model of an atom based on the Planck's quantum theory of radiation. The basic postulates of Bohr's theory are: An atom consists of a small, heavily positively charged nucleus around which electrons revolve in definite circular paths called orbits. These orbits a..

) molecules in precise orientations and to stabilize transition states in the making and breaking of bonds. Enzymes are highly specific. An enzyme usually catalyses a single chemical reaction or a set of closely related reactions. For e.g., urease catalyses the hydrolysis of urea only. Ot..
