Show how equation 20.33 reduces to a simpler form of an integrated first-order rate law when the reverse reaction of an equilibrium is negligible.
For a certain reaction, Ea is 135 kJ and H=45 kJ. In the presence of a catalyst, the activation energy is 39% of that for the uncatalyzed reaction. Draw a diagram similar to Figure 11.14 but instead of showing two activated complexes (two humps) show only one activated complex (i.e., only one hump) for the reaction. What is the activation energy of the uncatalyzed reverse reaction?
The following experimental data were obtained for the reaction of \'I14* and NOf in acidic solution.

Some bacteria are resistant to the antibiotic penicillin because they produce penicillinase, an enzyme with a molecular weight of 3104 g/mol that converts penicillin into inactive molecules. Although the kinetics of enzyme-catalyzed reactions can be complex, at low concentrations this reaction can be described by a rate equation that is first order in the catalyst (penicillinase) and that also involves the concentration of penicillin. From the following data: 1.0 L of a solution containing 0.15 g ( 0.15106 g) of penicillinase, determine the order of the reaction with respect to penicillin and the value of the rate constant. [Penicillin] (M) Rate (mol/L/min) 2.0106 1.01010 3.0106 1.51010 4.0106 2.01010
Assume that thermal decomposition of mercuric oxide, HgO, follows first-order kinetics. It can be followed by the production of oxygen gas as a product: 2HgO(s)2Hg(l)+O2(g) At a particular temperature, k=6.02104s1. If 1.00gram of HgO were present initially, how long would it take to produce a1.00mL of O2(g) at STP; b10.0mL of O2(g) at STP? STP = standard temperature and pressure for a gas.

The following is a quote from an article in the August 18,1998, issue of The New York Times about the breakdown ofcellulose and starch: “A drop of 18 degrees Fahrenheit [from77 °F to 59 °F4 lowers the reaction rate six times; a 36-degreedrop [from 77 °F to 41°F] produces a fortyfold decrease inthe rate.” (a) Calculate activation energies for the breakdownprocess based on the two estimates of the effect of temperatureon rate. Are the values consistent? (b) Assuming thevalue of Ea calculated from the 36° drop and that the rate ofbreakdown is first order with a half-life at 25 °C of 2.7 yr, calculatethe half-life for breakdown at a temperature of -15 °C.
