Collision theory is a principle of chemistry used to predict the rates of chemical reactions. It states that when suitable particles of the reactant hit each other with the correct orientation, only a certain amount of collisions result in a perceptible or notable change; these successful changes are called successful collisions.
Transition state theory explains the dynamics of reactions. The theory is based on the idea that there is an equilibrium between the activated complex and reactant molecules. The theory incorporates concepts from collision theory, which states that for a reaction to occur, reacting molecules must collide with a minimum energy and correct ...
Max Trautz (19 March 1880 – 19 August 1960) was a German chemist.He was very productive with over 190 scientific publications especially in the field of chemical kinetics.
Also called the probability factor, the steric factor is defined as the ratio between the experimental value of the rate constant and the one predicted by collision theory. It can also be defined as the ratio between the pre-exponential factor and the collision frequency , and it is most often less than unity.

Because it involves the collision of two NO 2 molecules, it is a bimolecular reaction with a rate which obeys the rate law = [()]. Other reactions may have mechanisms of several consecutive steps. In organic chemistry , the reaction mechanism for the benzoin condensation , put forward in 1903 by A. J. Lapworth , was one of the first proposed ...
According to collision theory, the frequency factor, A, depends on how often molecules collide when all concentrations are 1 mol/L and on whether the molecules are properly oriented when they collide. Values of A for some reactions can be found at Collision theory.
In 1918 he propounded his theory of chemical reaction which came to be called the "Collision Theory". A similar theory was also propounded by Max Trautz in Germany in 1916, unbeknown to Lewis because of the first World War. [1] In 1926 he was elected a Fellow of the Royal Society.
