If about 2.55 gallons of oil spills into the ocean per second, the first traces of color from an oil slick on the surface of water appear when the film reachs a thickness of 0.000150 mm and a dark sheet appears once the thickness grows to 0.0020 mm. How many days does it take for the oil to produce a dark sheet the size of 51885 mile squared?

Analysis of corrosion mechanisms and preventative measures
You have a solution of a buffer with 10 mMoles of the buffer. Initially the solution has a pH of 6.8. You add 100 mM kOH and the pH rises to 7.1. The pKa of the buffer is 6.3.
In a certain hypothetical experiment the initial concentration of reactant is 1.00 and its rate constant is 0.0150 . It follows a zero-order reaction mechanism for the consumption of . Plot the graph of concentration versus time. Take the time int..
