Quick Revision- CATALYST

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 Reaction

The Rate of a Chemical Reaction can be defined as the amount of the reaction which occurs in unit time. The rate of a reaction is measured by choosing certain properties of the reaction which will indicate how far the reaction has gone, and whose magnitude can be observed with time without disturbing the reaction. … Read more

Chemical kinetics

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

equilibriums

Chemical equilibrium Chemical equilibrium is a state in which the rates of the forward and reverse reactions are equal and the concentrations of the reactants and products remain constant. Equilibrium is a dynamic process i.e. the conversions of reactants to products and products to reactants are still going on, although there is no net change … Read more

Fast And Slow Chemical Reactions

 Slow reactions Chemical reactions that occur very slowly and can take a long time for completion are called slow reactions.  Usually covalent compounds are involved in slow reactions.Some reactions can take days, weeks and months to complete; they are called very slow reactions.For example, Milk may take several hours or a day to convert to curd, while it … Read more

Catalyst

Catalyst Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. ENZYMES are naturally occurring catalysts responsible for many essential biochemical reactions. Most solid catalysts are metals or the oxides, sulfides, and halides of metallic Elements and of the semimetallic elements boron, aluminum, and silicon. Gaseous and liquid catalysts … Read more
