The activation energy for a reaction is changed from 184 kJ/ mol to 59.0 kJ/ mol at 600. K by the introduction of a catalyst. If the uncatalyzed reaction takes about 2400 years to occur, about how long will the catalyzed reaction take? Assume the frequency factor A is constant, and assume the initial concentrations are the same.
Answer to relevant QuestionsThe rate law for a reaction can be determined only from experiment and not from the balanced equation. Two experimental procedures were outlined in this chapter. What are these two procedures? Explain how each method is used ...The thermal degradation of silk was studied by Kuruppillai, Hersh, and Tucker (“Historic Textile and Paper Materials,” ACS Advances in Chemistry Series, No. 212, 1986) by measuring the tensile strength of silk fibers at ...Experiments have shown the average frequency of chirp-ing of individual snowy tree crickets (Oecanthus fultoni) to be 178 min-1 at 25.0oC, 126 min-1 at 20.3oC, and 100. min-1 at 17.3oC. a. What is the apparent activation ...Consider the hypothetical reaction A + B + 2C → 2D + 3E In a study of this reaction, three experiments were run at the same temperature. The rate is defined as 2d[B]/dt.
