- The decomposition of many substances on the surface of a heterogeneous catalyst shows the following behavior: How do you account for the rate law changing from first order to zero order in the concentration of reactant?arrow_forwardCompare the functions of homogeneous and heterogeneous catalysts.arrow_forwardAt 573 K, gaseous NO2(g) decomposes, forming NO(g) and O2(g). If a vessel containing NO2(g) has an initial concentration of 1.9 102 mol/L, how long will it take for 75% of the NO2(g) to decompose? The decomposition of NO2(g) is second-order in the reactant and the rate constant for this reaction, at 573 K, is 1.1 L/mol s.arrow_forward
- Both technetium-99 and thallium-201 are used to image heart muscle in patients with suspected heart problems. The half-lives are 6 h and 73 h, respectively. What percent of the radioactivity would remain for each of the isotopes after 2 days (48 h)?arrow_forwardGaseous NO2 decomposes at 573 K. NO2(g) NO(g) + O2(g) The concentration of NO2 was measured as a function of time. A graph of 1/[NO2] versus time gives a straight line with a slope of 1.1 L/mol s. What is the rate law for this reaction? What is the rate constant?arrow_forwardThe following rate constants were obtained in an experiment in which the decomposition of gaseous N2O; was studied as a function of temperature.

- Bacteria cause milk to go sour by generating lactic acid. Devise an experiment that could measure the activation energy for the production of lactic acid by bacteria in milk. Describe how your experiment will provide the information you need to determine this value. What assumptions must be made about this reaction?arrow_forwardHydrogen peroxide and the iodide ion react in acidic solution as follows: H2O2(aq)+3I(aq)+2H+(aq)I3(aq)+2H2O(l) The kinetics of this reaction were studied by following the decay of the concentration of H2O2 and constructing plots of ln[H2O2] versus time. All the plots were linear and all solutions had [H2O2]0 = 8.0 104 mol/L. The slopes of these straight lines depended on the initial concentrations of I and H+.
