1010 - Temperature Dependence |
1002 - Define activation energy and explain how reaction temperature relates to reaction rate. |
1004 - Show the Arrhenius equation ( k = Ae^-Ea/RT ) and know R also equals 8.314 J/mol K. |
1006 - Show how taking the natural log of the Arrhenius equation leads to a linear equation relating ln(k) to 1/T. |
1030 - Calculate the activation energy from a plot of the natural logarithm of the rate constant versus inverse temperature, ln k vs. 1/T. |
1040 - Know and understand the collision model: atoms or molecules need to come in contact or collide in order to react. |
1050 - Apply the collision model to explain frequency factor, activation energy and orientation factor. |
1020 - Reaction Path |
1010 - Recognize heat of reaction is a state property, but rate of reaction is a path property. |
1020 - Know reactions occur in a series of events (steps) called a mechanism that combined define the reaction path. |
1030 - Recognize a balanced chemical equation is the sum of the elementary steps for that reaction. |
1040 - Identify the molecularity and write the rate law for an elementary step from the chemical equation for that elementary step. |
1050 - Define and label intermediary, transition state, heat of reaction and activation energy on a reaction coordinate diagram. |
1060 - Define rate-determining step (RDS), identify RDS by its relative rate, use the RDS to determine the rate law for a reaction. |
1070 - Find the overall rate law (in terms of only starting materials) when a RDS is not the first step of the reaction. |
1080 - Demonstrate if a proposed mechanism is consistent with an observed rate law. |
1030 - Catalysis |
1010 - Explain how a catalyst increases the rate of a reaction without being consumed. |
1020 - Relate catalytic activity to activation energy, reaction mechanism, and transition state stability. |
1030 - Recognize an automobiles catalytic converter elimenates exhaust molecules by catalyzing production of less harmful emissions. |
1040 - Differnatiate between and identify homogeneous and heterogeneous catalyists. |
1050 - Recognize the role of catalysts in atmospheric reactions including depletion of the ozone layer and the interconversion of pollutants. |
1060 - Explain the general model of enzymes and understand their role as biological catalysts. |
