Science Investigation RATES OF REACTION Secondary resources From research I can find out the factors that affect the rate of reaction. Collision Theory. A chemical reaction can only occur between particles when they collide (hit each other). Particles may be atoms, ions or molecules. There is a minimum amount of energy which colliding particles need in order to react with each other. If the colliding particles have less than this minimum energy, then they just bounce off each other and no reaction occurs. This minimum energy is called the activation energy. The faster the particles are going, the more energy they have. Fast moving particles are more likely to react when they collide. You can make particles move more quickly by heating them up (raising the temperature). Changing the Rate of a Reaction. There are 5 ways to increase the rate of a chemical reaction. They are all understood in terms of Collision Theory. The rate of a...
