Final Jeopardy Describe how concentration and temperature are related to the rate of a chemical reaction. Thenidentify and describe one more factor that can affect reaction rate.
Template byBill Arcuri, WCSD
Click Once to BeginWhat is
Concentration describes the number of particles in a given volume. As the concentration of the reactants increases, there are more particles to collide and react with one another. This can increase the reaction rate. Temperature is related to the rate of a reaction. Temperature is also related to energy. When you add energy to a reaction, it increases particle motion. This increase in motion is measured by an increase in temperature. Reactions at higher temperatures have reactant particles that are moving faster. This results in more reactant collisions and a faster reaction rate. Surface area of the reactants can also affect the reaction rate. Increased surface area means that more of the surface of the reactant is exposed. As surface area increases, the rate of the reaction increases as well.
