- Rates of Reaction BACKGROUND INFORMATION What affects the rate of reaction. 1) The surface area of the magnesium. 2) The temperature of the reaction. 3) Concentration of the hydrochloric acid. 4) Presence of a catalyst. In the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride.

- Rates of Reaction Reactions Reactions can only occur when two different particles come together. The theory for the way the reaction occurs is called The Collision Theory. The collision theory states that that the different particles need to collide with each other in order to react. Rates of reaction GCSE COURSEWORK CHEMISTRY AIM In the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride. The hydrogen ions give hydrochloric acid its acidic properties, so that all solutions of hydrogen chloride and water have a sour taste; /5(3).

Changing the pressure; In this particular investigation I am going to find out how heat affects the rate of reaction in the reaction of Reviews: Rates of Reaction Coursework Plan During this investigation I am going to add dilute hydrochloric acid to calcium carbonate (powder), but vary the volume of acid. I am also going to collect the amount of gas given off, and to record the results (time) it takes for the gas to finally disappear. After.
