4. Bioremediation is a process where bacteria are deployed to mitigate an environmental disaster, such as an oil spill. The efficiency of bacteria for destroying oil (hydrocarbons) depends on many environmental factors. When cleaning a certain oil spill it was found that the bacteria remove oil in a second-order process (with respect to the oil) with a rate constant of 2106M1s1. Assume the initial concentration of the oil is 3.5104M. (a) How many days does it take the bacteria to remove 90% of the oil from the water? (b) What is the first half-life for the decomposition of the oil by the bacteria? (c) What is the second half-life for the decomposition of the oil by the bacteria
