INTRODUCTION: The rate of reaction can be defined as the rate of lost of reactants or the rate of formation of a product during a chemical change. The rate of reaction depends on four things: * Temperature * Concentration (or pressure if the reactants are gases) * Catalyst * Surface area * Increased rate means quicker reaction. The increased rate could be due to any of these: * Increase in temperature * Increase in concentration * Catalyst added * Solid reactants crushed up into smaller bits We are going to investigate concentration. "All four methods of increasing the rate of reaction can be explained in terms of increasing the number of collisions between the reacting particles" From GCSE revision book "The rate of reaction can be measured in three ways: * Precipitation: this is when the product of the reactions is precipitated which clouds the solution. Observe a marker through the solution and measure how long it takes to disappear. * Change in Mass:...
