Aim: To find the effects of change of the variable on a reaction between Magnesium and Hydrochloric acid Reactions occur when Hydrochloric acid particles collide with the Magnesium. They all work by increasing the number of Magnesium collisions. There are a number of factors that change the speed of a reaction: * Temperature * Concentration of Hydrochloric acid * Surface area * Addition of a catalyst To make a choice for this experiment we have to choose which is the most feesable in the circumstances. Temperature: Temperature will affect the rate of reaction because an increase will speed up the movement of the Particles so that they collide more frequently. However, it is not a good option in the circumstances because the required amount of variations is 5, and using an icebox, room temperature and heating (we would not be able to keep different levels of heat constant) gives us only three variations. In addition, the reaction...
