Bioremediation is the process by which bacteria repair their environment in response, for example, to an oil spill. the efficiency of bacteria for "eating" hydrocarbons depends on the amount of oxygen in the system, ph, temperature, and many other factors. in a certain oil spill, hydrocarbons from the oil disappeared with a first-order rate constant of 2×10−6s−1. how many days did it take for the oil spill to decrease to 10 % of its initial value?
