Reaction Rates

Introduction of collision theory According to this theory, a chemical reaction only takes place when two reacting molecules collide with sufficient kinetic energy. The reacting molecules collide with each other to perform a reaction. But not all the collisions are effective. When the reacting molecules collides with proper orientation and with sufficient kinetic energy, then … Read more

Arrhenius Equation Definition Generally we know that the increase of temperature of a reaction, the reaction rate increases. Normally the reaction rate is doubled by the increase of temperature by 10 oC. In 1989 Arrhenius suggested a simple relation between the reaction rate and the temperature of a reaction. The Arrhenius equation is written as: ……………………….(i) … Read more
