Chemistry Notes CH 16: Kinetics: Rates and Mechanisms of Chemical Reactions Includes: Reaction Rates, Rate Orders, Catalysts, Reaction Mechanisms, Activation Energy, and the Arrhenius Equation. Corresponding Textbook: Chemistry; The Molecular Nature of Matter and Change (7 edition) Key Concepts:  Reaction Rate: change in concentrations of reactants/products over time. It is affected by: 1. Concentration of reactants Increasing concentration of reactants= increased collision frequency of molecules= increased reaction rate. 2. Physical states of reactants A physical state that is more spread out has a greater surface area= increased contact between reactants= increased reaction rate 3. The temperature of the reaction Increased temperature= increased collision frequency= increased reaction rate 4. Use of a catalyst Catalysts lower the activation energy= increased reaction rate **Note: changing the concentrations of reactants changes the reaction rate NOT the rate constant (k).  Rate Orders: There are three different orders of reaction rates: zero, first, and second. Important to know what the characteristics and equations are for each type. Characteristic Zero Order First Order Second Order Differential Rate=k Rate=[k] Rate=k[A]^2 Rate Law Integrated [A]= -kT+[A] 0 ln[A]=- 1/[A]=1/[A] 0 Rate Law kT+ln[A] 0 +kT Straight Line Plotting [A] Plotting ln[A] Plotting 1/[A] Graph versus time versus time versus time gives a gives a gives a negative slope negative slope positive slope of value k of value k of value k Half-Life T1/2A] /20 T 1/2693/k T1/2/k[A] 0 Rate constant mol/s 1/s 1/M*s (K) Units Key Terms:  Activation Energy: the energy level the colliding molecules must overcome for the reaction to occur. Reversible reactions have two activation energies; one for the forward reaction and one for the reverse reaction. H rxn afwdE arev ∆  Reaction Mechanism: a sequence of elementary steps that make up an overall reaction. They are characterized by their molecularity. For elementary steps, the equation coefficients are the reaction orders in the rate law. The overall rate law only includes species up to and including the slow step.  Rate Determining Step: the slowest step in the mechanism that limits the overall speed.  Reaction intermediate: a substance formed and used up during the reaction.  Catalyst: speeds up the reaction rate without being consumed. They stabilize the reaction’s transition state. ∆H isn’t affected by the catalyst. Catalysts can be heterogeneous or homogenous depending on the phase of the catalyst.  Enzymes: the substrates collide with the active site and attach by IMF to cause a chemical reaction. Very efficient as catalysts but highly specific. For Example: if the catalyst exists in the solution with the reactants it is homogenous.  Arrhenius Equation: uses the rate constant (k), gas constant (R=8.314 J/K*mol), Temperature, the activation energy and the Arrhenius variable (A) which accounts for the molecular orientation (includes probability factor and the collision frequency). Equation can be written either: −Ea k2 Ea 1 1 k=Ae RT OR ln = ( − ) k1 R T 1 T2
