QUICK REVISION TOPIC: Catalyst Definition: Increases or decreases the rate of reaction without actually taking part in the reaction. Types: On the basis of phase of reactants: Same phase : Homogenous catalyst; eg: In Hydrogenation use of Raney nickel catalyst Different phase : Heterogenous catalyst; Eg in Ozone Depletion Chlorofluorocarbons (CFCs) like … Read more
Chemical kinetics Chemical kinetics is that branch of chemistry which deals with the study of the speeds or the rates of chemical reactions, the factors affecting the rates of the reactions and the mechanism by which the reactions proceed. It concerns itself with the measurement of rates of reactions proceeding under the given conditions of … Read more
Ore An ore is a special type of rock that contains a large enough amount of a particular mineral (usually a Metal) to make it economically practical to extract that mineral from the surrounding rock. Not all Minerals are found in a large enough amount in one location to make it worth it to remove the ore … Read more
ENZYMES Enzyme, a substance that acts as a Catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process. The biological processes that occur within all living organisms are chemical reactions, and most are regulated by enzymes. Without enzymes, many of these reactions would not take place … Read more
