Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By
