Theories of Chemical Kinetics

Theories of Chemical Kinetics: Arrhenius Equation is a purely experimental equation that gives a reasonably good representation of temperature depending on the rate constant. There are two common theories of reaction rates leading to the formation of the Arrhenius Equation. They are- Collision Theory. Transition State Theory. Collision Theory: This theory considers that the collision between …

Explanation of Increase in the Rate of the Reaction with Temperature

Increase in the Rate of the Reaction with Temperature: According to the collision theory of chemical reaction, the rate of reaction depends upon- Collision Frequency (Z). Fraction of Effective Collisions (f). The effect on these two quantities, which affect the rate of reaction, by a change in temperature is described below- (1) Increase in Collision Frequency- …

Difference Between Order of Reaction and Molecularity of Reaction

Order of Reaction and Molecularity of Reaction: The following are the points of difference between the order of reaction and molecularity of reaction. Order of Reaction Molecularity of Reaction It is the number of reacting molecules whose concentration actually changes during the reaction. It is the number of reacting species as indicated by the balanced chemical …

Factors Affecting the Rate of Reaction

Factors Affecting the Rate of Reaction: The rate of any particular reaction depends upon the following factors- Concentration of Reactants- The rate of reaction depends upon the concentration of the reactants. This is clear from the Law of mass action, according to which the rate of reaction is directly proportional to the active mass or molar …
