Rates of Reaction: AIM: To record the rate of reaction between Hydrochloric Acid (HCl) and Magnesium (Mg). Hydrochloric Acid + Magnesium Magnesium Chloride + Hydrogen 2HCl + 2Mg MgCl2 + H2 PREDICTION: I think that if I keep the magnesium the same length and weight as to keep an equal surface area and change the concentrations of hydrochloric acid, then the highest concentration will react the quickest. This prediction is due to my knowledge of the 'collision theory'. The 'collision theory' explains how the rate of reaction is affected by three variables: * Variable 1 - Surface Area; * Variable 2 - Temperature; * Variable 3 - Concentration. * I am focusing on the concentration part and the 'collision theory' states that if the acid concentration is low, it has fewer particles in it. Therefore, there is less chance of collisions, which results in a slow reaction. The theory continues to say that if the acid...
