Collision Theory of Chemical Reaction An Overview and Collegedunia

Collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species atoms or molecules to come together/collide with each other The rate of the reaction in collision theory depends on the frequency of collisions The theory also tells us that reacting particles often collide without reacting

Social Reaction Theory 1114 Words Internet Public Library

The Collision Theory Of Chemical Reaction ipl org

Why this chemical reaction occurs and what mechanistic and energetic aspect are involved in it are explained by a theory named the collision theory of chemical reactions It was developed by British scientist William Lewis and German chemist Max Trautz in around 1916 1918 The collision theory is somewhat based on kinetic theory of gases THE
