Question

1) Use Kinetic Molecular Theory to explain how temperature affects the rates of chemical reactions. Be detailed in your explanation.

Answer 1

According to kinetic molecular theory the average kinetic energy of gas particles is propertional to absolute temperature.

When two chemicals react with each other, Definitely Collision will occur in between their molecules . For that they need sufficient energy for the reaction to take place. This is the phenomenon of collision theory. The two molecules will only react if they have sufficient energy. By heating the mixture, you will raise the energy levels of the molecules involved in the reaction. Increasing temperature means the molecules move faster that means they will gain kinetic energy which is a part of kinetic theory. In a chemical reaction, If the temperature will be increased then rate of reaction will be fast and if the temperature will be decreased then rate of reaction will be slow.
