1. How does the initial reactant concentration affect: o the initial reaction rate? o the overall reaction order? o the rate constant? 2. How does the temperature affect: o the initial reaction rate? o the overall reaction order? o the rate constant? 3. How can the instantaneous rate of reaction be determined from the graphs? 4. How can the overall reaction order be determined from the graphs? 5. How can the rate constant be determined from the graphs? 6. Under what conditions does the rate constant remain constant? 7. Increasing the concentration of reactant or temperature of a chemical reaction will increase the reaction rate. This is due to the fact that raising concentration and temperature almost always ensures more collisions betweens the reactants in the system. Raising the concentration will create more collisions because there are simply more of the reacting molecules in the same amount of space. Raising the initial temperature of the system will raise the kinetic energy of the molecules, and thus there will be more
