Please answer with explanation:
Collision theory is used to explain how chemical species undergo a reaction. Using this theory and kinetic molecular model which of the following does not influence the rate of a chemical reaction?

Dear student,

Collision theory is used to predict the rates of chemical reactions. It is based on the assumption that for a reaction to occur it is necessary for the reacting species i.e. the reacting atoms or molecules to come together and collide with each another. However, not all collisions will bring about chemical change. A collision will be effective in producing chemical change only if the species brought together possess a certain amount of internal energy, equal to the activation energy of the reaction. The colliding species must be oriented in a proper geometry for effective collisions. The rate of reaction also depends on the kinetic energy of the reactant molecules and we know that kinetic energy as higher the velocity and temperature, higher will be the kinetic energy.

Thus, the answer will be 'all of the above influence the rate'
