RATES OF CHEMICAL REACTIONS AIM: To find out how changes in concentration of a solution affect the rate of the reaction. INTRODUCTION: Chemical reactions occur all a round us. Some reactions are slow, like iron rusting and some are fast like potassium reacting with water or paper burning. There are several factors that affect the speed of a reaction: concentration of solutions, surface area of solids, temperature of reactants, the presence of a catalyst, the pressure of gasses Before I consider each of the above factors we need to look at the nature of matter. We all know that water can exist as ice (solid), water (liquid), or water vapour (gas). These are three states of matter, solid, liquid and gas. KINETIC THEORY This explains how all matter is made up of tiny particles and how these particles are arranged. In a solid the each particle is strongly attracted to all other particles so the...
