PROJECT QUESTION Investigating factors that affect the rate of a reaction A chemical reaction is when substances chemically reacts to produce a new substance. The rate of a reaction is the number of chemical reactions per second. There are 4 factors that affect the rate of a chemical reaction. They are:> Temperature> Surface area> Concentration of solution> Catalyst AIM To investigate experimentally the effects of the concentration of a solution on the reaction rate of calcium carbonate, using 5 different solutions of HCl. Figure 1- Diagram of apparatus used in this investigation SCIENTIFIC THEORY The equation for the reaction is: CaCO3 + 2HC l CaC l2 + CO2 + H2O When reacting particles gain enough energy they vibrate and move faster. This initial energy is known as the activation energy, and it is needed to break the initial bonds. Before they can react, molecules, atoms or ions have to bump into each other and the collision must be hard enough...
