Rates of Reaction Coursework Robert Flack 2002 0072 class 11KN Aim The aim of this investigation is to find out the factors which affect the rates of reaction between magnesium and hydrochloric acid. Equation: Mg(s) + 2HCl(aq) --> MgCl²(aq) + H²(g) Magnesium will react with hydrochloric acid, because it is higher in the reactivity series that hydrogen. When the two chemicals react a displacement reaction will take place and the magnesium will displace the hydrogen in the hydrochloric acid forming magnesium chloride and hydrogen gas. Prediction Given the collision theory, I predict that the higher concentration of hydrochloric acid, the faster the reaction. This is due to the fact that there are more molecules in the acid likely to collide with the magnesium. The rate of reaction also relates to the surface area of the magnesium, the bigger the area the greater chance of collision and thus the faster the reaction takes place. I also predict that the...
