What is the purpose of chemical reactions? Why do chemical reactions involve a change in energy? How does temperature affect chemical changes? What factors influence chemical reactions? Why are chemical equations important in chemical changes? How do catalysts affect the rate of a chemical reaction?
The collision theory is the theory that best explains how various factors affect the rate of a chemical reaction. Generally, the factors affect the physics of the reacting particles which have to collide in the right orientation in order to produce a successful reaction.An...
