Bioremediation is the process by which bacteria repair theirenvironment in response, for example, to an oil spill. Theefficiency of bacteria for “eating” hydrocarbons dependson the amount of oxygen in the system, pH, temperature,and many other factors. In a certain oil spill, hydrocarbonsfrom the oil disappeared with a first-order rate constant of2 x 10-6 s-1. At that rate, how many days would it take forthe hydrocarbons to decrease to 10% of their initial value?

The label on a bottle of 3% (by volume) hydrogen peroxide, H2O2, purchased at a grocery store, states that the solution should be stored in a cool, dark place. H2O2decomposes slowly over time, and the rate of decomposition increases with an increase in temperature and in the presence of light. However, the rate of decomposition increases dramatically if a small amount of powdered MnO- is added to the solution. The decomposition products are H2O and O2. MnO2 is not consumed in the reaction. Write the equation for the decomposition of H2O2. What role does MnO2 play? In the chemistry lab, a student substituted a chunk of MnO2 for the powdered compound. The reaction rate was not appreciably increased. WTiat is one possible explanation for this observation? Is MnO2 part of the stoichiometry of the decomposition of H2O2?

In the experiment, below gas-phase homogenous oxidation, k 2 NO + O2 -------> 2NO2 was confirmed to have the third-order kinetics, showing an elementary reaction, at least for low partial pressures of nitrogen oxides. However, the rate constant k actually decreases with increasing absolute temperature, indicating an apparently negative activation energy. It is known that any elementary reaction must have a positive energy. Provide an explanation, starting from the fact that an active intermediate species, NO3, is a participant in some other know reactions that involve oxides of nitrogen. Other active intermediates could be NO* and O2* and O* (oxygen atom). Using chemical reactions, or reaction pathway, to describe the mechanism, and using your own reactions suggest how to postulate the formation rate of NO2.
