Science Coursework How does the concentration of acid affect the rate of reaction? Aim To find out if the concentration of Hydrochloric acid affects the time it takes for a reaction to complete. Prediction I predict that the more concentrated the Hydrochloric acid or any acid, the faster the rate of reaction. Introduction Reaction rate = mass ÷ time taken In These points illustrates four important factors which affects the rate of chemical reactions:> Surface area> Temperature> Concentration> Catalysts In this experiment, the surface area can be controlled by using 5cm piece of magnesium ribbon for each experiment. The concentration of acid will vary as this will help to conclude if the concentration of acid affects the time it takes to dissolve the magnesium. There is no catalyst to speed up the rate of reaction and also the temperature can not be controlled, e.g. the room temperature may vary when the experiment is carried out. * Surface Area The...
