The following data were collected to measure the kinetics of oxygen aeration into wastewater. [O2(aq)]sat equaled 7.00 mg/L during the test. (a) Determine if the data are best fit by a zero-order, first-order, or first-order saturation-type rate expression. Show appropriate graphs and regression fits to justify for your answer (b) Report the correct rate constant in the correct units.
