An investigation into the factors that affect the rate of reactions Aim My aim is to find out how concentration affects the rate of the reaction between the compound calcium carbonate (in the form of marble chips) and the solution hydrochloric acid. Variable selected During the experiment I am going to change the concentration of the hydrochloric acid by adding water at varied ratios. Variables kept constant For the experiment I am going to keep the mass of marble chips constant and attempt also to keep the surface area of the marble chips constant (by picking ones that look similar and are roughly the same size, shape and mass). I am also hoping to keep the time I am allowing the reactants to react constant, the temperature constant and the pressure within the conical flask constant. Prediction After studying reaction rates I predict that by doubling the concentration of the acid during the experiment the rate of reaction...
