Students identify how factors such as temperature, concentration, and surface area can affect the rate of a chemical reaction. They use the collision model to explain changes in chemical reaction rates. Students discuss how a catalyst is a substance that changes the rate of a chemical reaction but is not changed in the reaction. Full Review »
