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
The Rate of a 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 … Read more

Motion Motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance, velocity, acceleration, time and speed. The branch of physics which deals with the study of motion of material objects is called mechanics. Mechanics is divided into following branches. (i) Statics : Statics … Read more
