Rates of Reactions. Aim: - To show that different variables can change the rate of reactions e.g. make them faster or slower. Theory: - That changing the variables in a reaction such as concentration, temperature and surface area will increase or decrease the rate of reaction. This would happen because, if you changed the concentration of a solution to a higher concentration the rate of reaction would increases, as there are more particles in the solution which means the particles would collide more. As they are colliding more, particles collide with the other substance making the reaction time much farter and greater. Low Concentration = Slower Reaction High Concentration = Faster Reaction Less Particles More Particles Equipment:- Chronicle Flask Measuring Cylinder Gas syringe Beaker Calcium Carbonate Stopwatch Pestle and Mortar Boss and Clamp Hydrochloric Acid Clamp stand But and Tube Measuring Scales Safety: - As acid and Bunsen's may be being used safety goggles should be worn...
