Reaction Rates Investigation Aim: The aim of this investigation is to find out how the concentration of hydrochloric acid will affect the reaction rate of hydrochloric acid and magnesium ribbon. Prediction: I predict that as the concentration of hydrochloric acid increases so too will the reaction rate. The reasons for this can be explained using the collision theory. This claims that the more particles there are moving around in one place the more chance there is of a collision between the particles with sufficient energy to create a reaction. In the higher concentrations of hydrochloric acid there is more acid particles to collide with the magnesium therefore a higher rate of reaction. Other factors that affect the rate of reaction are; temperature, catalysts and surface area. Temperature affects reaction rates as it dictates how much energy the particles in a substance have, at higher temperatures particles have more energy and so move more quickly...
