Know the definition of the van’t Hoff factorChapter 16 1. Review logarithms2. Express the rate of a reaction in terms of the relative rates of disappearance of reactants and formation of products for a chemical reaction.3. Know the difference between “average rate” and “instantaneous rate”. 4. Derive the rate law for a reaction from experimental data.5. Understand and be able to use the term “rate constant”.6. Use the rate law to calculate the rate, rate constants, or reactant concentrations.7. Determine the order of a reaction.8. Use the integrated rate laws for zero, first, and second order reactions to determine:• the concentration of a reactant or product at any time after a reaction has started• the time required for a given fraction of sample to react• the time required for a reactant concentration to reach a certain level9. Know how the integrated rate laws can be used graphically to determine the order of a reaction.10. Understand and correctly use the concept of half-life.11. Understand how the collision model accounts for reaction rates.12. Understand the concept of activation energy, and know how it relates to the variation of reaction rate with temperature.13. Be able to draw a reaction energy profile for a given reaction, identifying:• reaction coordinate • transition state • activation energy• endothermic/exothermic reactions14. Use the Arrhenius equation to determine the activation energy for a reaction.15. Understand what is meant by the mechanism of a reaction using the terms elementary steps, rate-determining step, and reaction intermediate.16. Determine the molecularity of an elementary step.17. Given the mechanism of a reaction, including the rate-determining step, determine the rate law for that reaction.18. Understand how catalysts work, and be able to identify the roles played by heterogeneous and homogeneous
