What are the factors influencing rate of reaction
Dear Student,
Factors influencing rate of reaction are as follows:
(a) Nature of the Reactants: Chemical reactions in an aqueous solution take place almost immediately. It is because the molecular bonds in the molecules of reactants are broken down. The attractive forces between the ions are broken and the ions become hydrated by the water molecules.
(b) Temperature of the Reactants: The rate of a reaction increases with increasing temperature. Each time the temperature is increased by 10°, the rate of reaction doubles.
(c) Concentration of the Reactants: The rate of reaction will increase as the concentration of the reactants increases. Increasing the concentration of a reactant means increasing the number of reactant molecules that are in that same volume.
(d) Presence of a Catalyst: A Catalyst is a substance that increases the rate of reaction without actually participating in the reaction. Catalysts work by providing an alternate pathway for the reaction. It is the one which requires less energy for the reactants to convert into products. Some catalysts increase the rate of more than one type of reactions whereas catalyst like the enzymes in our bodies is specific to just one reaction or even one single type of reactant molecule. Therefore, a catalyst increases the rate of reaction.
