Order of Reaction

by

The reaction rates vary with the concentration of the reactants. The experimental results show that the reaction rates do not always show similar concentration-dependences. In many cases, the rates are found to be proportional to the first power of concentration. There are many reactions in which the rates varied to the second or even third … Read more

Factors Influencing the Rate of Reaction

by

The rate of reaction is governed by number of factors. Those having appreciable effect are described below: a) Nature of reactants Reactions involving polar and ionic substances including the proton-transfer reactions are usually very fast. On the other hand, the reactions in which bonds are rearranged, or electrons transferred, are slow. Oxidation- reduction reactions, which … Read more
