Jon Leary 11SA Rates of Reactions - Coursework Hypothesis The rate of a reaction increases with concentration. Prediction I predict that when the concentration of the acid is raised, the rate of the reaction will increase. This is because, when the concentration of acid is higher, more acid particles are present in a given volume of the solution, therefore, more acid particles are available to collide with magnesium particles. This consequently increases the chances of successful collisions (those resulting in a reaction) occurring. As the collision theory states, the more collisions that occur in a period of time, the faster the rate of the reaction. This is because the reaction only occurs when acid and magnesium particles collide and successfully join together to form magnesium chloride and hydrogen particles. In a previous experiment with acid and marble chips, I found that higher concentrations of acid increased the rate of reaction quite significantly. About the Reaction The reaction...
