Which of the following is NOT important as a contributing factor to photochemical smog? stagnant air rsunlight a lot of traffic rrigation For the reaction 3 A 5B-2C+4D, the rate of the reaction in terms of written as would be r_1A[A [A] Which statement below regarding the average rate of a reaction is FALSE? The change in concentration of reactant or product is not always linear with time The average reaction rate usually decreases as the reaction proceeds. The average reaction rate can be determined from the slope of the tangent line drawn at time 0 on a plot of concentration versus time The average rate usually depends on the concentrations of reactants A runner fnishes her 8 mile run with an overall pace 9.45 min/mile. At mile 6, she encounters a hill, and her pace slows to 11:20 min/mile In considering this scenario as an analogy to reaction rates, the mile 6, 11:20 min/mile data point is comparable to (Hint: see p. 566 in the textbook) an instantaneous rate an average rate C rate law

rate constant Sometimes chemical reactions have all the reactants but one present at such overwhelmingly high concentrations that they do not significantly change during.the. course.of a reaction To simplify kinetic calculations, chemists may use a rate law for the single, low concentration limiting reactant that is what order? zero order first order pseudo first order second order According to kinetic molecular and collision theory, the rates of a chemical reaction and the fraction of reactant molecules that can surpass the activation energy barrier should with increasing temperatures decrease increase remain the same lose kinetic energy
