SCIENCE COURSEWORK RATES OF REACTION. INTRODUCTION. Reactions happen when the reactant particles collide and turn into a product. Sodium and chlorine, when reacted, they give us a compound Sodium Chloride (salt). Chemical reactions can be very difficult to undo. When metal rust this is a slow reaction, however burning, this is very quick. A speed on which the reaction takes place is called and rate of reaction. There are many ways on which to speed up the reaction. The most common is to speed up the collision between the particles. The more collisions per second the faster the reaction will be. To speed up chemical reactions; INCREASE THE TEMPRETURE Reactant particles hit each other harder because they have more energy in them. Also the temperature increase makes the particles grow more so the frequency of collisions increases. INCREASE THE CONCENTRATION This only works with a solution, increasing the solution makes the particles closer together, so the collision frequency...
