... Introduction In this project I am going to investigate rates of reaction of an indigestion tablet when added to hydrochloric acid. The variable I am going to use will be the temperature of the acid. (All background knowledge used in this project was taken from previous experience - notes and experiments from work done in year nine) What are rates of reaction? The rate of a reaction is the speed at which a reactant is turned into the product. Chemical reactions can take place at very different rates (eg. explosions, rock formations). A rate is measured as: A change in something (eg. loss of mass/mass of gas given off) Divided by The time it takes to change/disappear Rates of reactions can be measured in two different ways: * How fast reactants disappear * * How fast products appear Many factors affect rates of reaction: * Surface area The greater the surface area of a solid, the greater the area of the particles that is
