Magnesium + Hydrochloric Acid Magnesium Chloride + Hydrogen Mg(s) + 2HCl(aq) MgCl(aq) + H2 (g) There are four main factors which may affect rate of reaction. These are: - 1. Concentration 2. Temperature 3. Catalyst 4. Surface area CONCENTRATION- if the concentration of the acid is increased, the rate goes faster. In a concentrated acid there are more particles in it this means that there is a more chance of successful collisions occurring. If the acid was diluted,...
