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?
