10th February raheem hussain 11w1 How CONCENTRATION Affects The Rate of Reaction of Hydrochloric Acid and Magnesium Ribbons Aim:I am going to investigate the effects of concentration on the rates of reaction Introduction: Factors affecting the rates of reaction are * Surface area * Concentration * Pressure * Temperature * Adding Catalyst The reaction that I am going to be looking at is between a metal, magnesium strips and an acid, hydrochloric acid. The result of these two reacting would leave me with a salt, which would be magnesium chloride and a gas, which will always be hydrogen. The word equation for this reaction is: Magnesium+Hydrochloric---- Magnesium+Hydrogen Acid Chloride The symbol equation for this is: Mg+2hcl----- MgCl2+h2 Concentration: If the concentration of any reactant in a solution is increased, the rate of reaction is increased o Increasing the concentration, increases the probability of a collision between reactant particles because there are more of them in the same volume. ? * Increasing...
