effective interest rates

A catalyst has no effect on the value of the equilibrium constant of a reaction. This is because, a catalyst affects the rates of forward and backward reactions to the same extent. A catalyst however, helps in attaining the state of equilibrium faste..

Catalysts are substances, which alter the rate of chemical reactions without undergoing any overall chemical change themselves. In the manufacture of ammonia, iron is used as a catalyst and it enhances the rate of this reaction. as a catalyst. Sometimes catalysts are used to..

Frictional Effects - An oscillator, in actual practice, almost always lies in a resisting medium, like air, oil etc., where part of its energy is dissipated in overcoming the opposing frictional or viscous forces and its amplitude, therefore, goes on decreasing progressively. Such forces,..
