Unit Objectives: At the end of this K, E, T unit,
I can explain how various factors (temperature, agitation, concentration, surface area, and catalysts) affect the rate of a chemical reaction as well as the manner in which this occurs (the collision theory). (CK12 Sections 18.1, 18.2, 18.3, 18.5, 18.6)
I can interpret reaction mechanisms to explain an overall reaction and identify intermediates & catalysts. (CK12 Sections 18.11, 18.12, 18.13, 18.14)
I can interpret a potential energy diagram and explain how it changes with the presence of a catalyst. (CK12 Section 18.4, 18.6, 18.15)
I can differentiate between endothermic and exothermic reactions. (CK12 Sections 17.1, 17.2, 17.3, 17.4)
I can write & solve for the K expression for a chemical reaction/process and use it to predict whether the reaction favors the reactants or the products. (CK12 Sections 19.1, 19.2, 19.3, 19.4, 19.5)
I can explain LeChatelier’s principle and predict what will happen to the concentrations of all components in the chemical reaction when a system at equilibrium is subjected to a stress. (CK12 Sections 19.6, 19.7, 19.8, 19.9)
I can predict if the K increases, decreases, or remains the same once the shift in equilibrium has been reestablished. (CK12 Section 19.10)
I can describe and explain the law of conservation of energy. (CK12 Sections 17.1, 17.2)
I can describe entropy and explain how it is used to drive a reaction. (CK12 Sections 20.1, 20.2, 20.3)
I can describe enthalpy and explain how it is used to drive a reaction. (CK12 Sections 17.10, 20.3)
I can calculate enthalpy using heats of products/reactants, Hess’ Law, Heats of Formation, and Bond Energies. (CK12 Sections 17.15, 17.16, 17.17, 17.18, 17.19)
I can calculate Gibbs’ free energy and use the value to determine if a reaction is spontaneous or nonspontaneous. (CK12 Sections 20.4, 20.5, 20.6, 20.7)
