Science Coursework - What factors effect the rate of reaction between magnesium and hydrochloric acid? Background Knowledge There are four factors that can affect the rate of reaction and they all rely on the collision theory. This is basically how hard and how often particles collide with each other. The more and harder they collide, the faster the reaction time will be. If the acid is made more concentrated there are more particles, which means collisions are more likely. So, the higher the concentration, the quicker the reaction time is. Temperature also affects the rate of reaction. If the temperature is increased, the particles move quicker so more collisions happen. This means the higher the temperature, the quicker the reaction time. Adding a catalyst increases the number of collisions by giving the reacting particles a surface to stick to where they can collide more often, although in this experiment there are no catalysts. The last factor...
