How many different materials can you see in this bedroom?. Lecture 14 . Reaction Rates. Recall that we defined the rate of reaction as the rate of production of the products, or equivalently, the rate of consumption of the reactants.. Reaction rates for elementary reactions depend on:. Add the new notes to your . table of contents. , and then turn to the next clean page and set up your title and date. Tape the two slides into your INB flat down, directly under your title - they do not need to flip up. By: Abby . Marstiller. , Paulina . Pullin. , Emily . Henline. What is a chemical reaction?. A chemical reaction involves the making or breaking of bonds between atoms. . The total number of atoms remains the same but the combinations are different. . Chemical Reactions. :. A . chemical reaction . is a process that changes one set of chemicals into another by rearranging chemical bonds. The elements you start with are . reactants. The elements you end with are . THINK ABOUT IT . Living things are made up of chemical compounds, but chemistry isn’t just what life is made . of—chemistry is also what life does. . .
