The temperature of a gas is raised by 10 ? C, the collision frequency increases by 2 %, but. Why reaction rate is increases by about 100 % or more. Concept introduction: The rate of reaction depends upon the temperature. With a raise of 10 ? C, frequency of collision increases slightly but the rate of reaction increases by about 100 % or even more, this is due to increase of effective collision between the reactant molecules. All molecules must possess some kinetic energy called Threshold Energy. In order to expect the products from reactants, molecules must have some extra energy called Activation Energy. Hence in any chemical reactions , if a molecule or reactants become products must have this activation energy. Also, if we increase the temperature slightly in the reactions, molecules can perform effective collision among themselves and the rate of the reaction is enormously increasing (100%). Hence a molecule must possess Activation Energy along with effective collision will always leads to products.
