Chemistry coursework An experiment to show how the concentration of an acid can affect the rate of reaction. The Planning... My aim: To investigate whether the concentration of an acid can affect the rate of reaction between 1M of hydrochloric acid and marble chip. The Reaction... CaCO3 + 2HCl = CO2 + H2O + CaCl2 Calcium carbonate + hydrochloric acid = Carbon dioxide+ water + calcium chloride Scientific Knowledge: the collision theory For a reaction to take place the particles in the substances need to collide with enough energy, this is called activation energy. This is known as the collision theory, however if there is anything that can increase or decrease the chance of a collision this can also change the rate a reaction can take place. Examples of variables that can affect reaction: o The concentration o Whether there is a catalyst o Temperature o Surface area Concentration? There are more reactant particles therefore when they collide in the...
