You have a 1.00 m sample of landfill leachate containing a high concentration (1 M) of perfluorooctanoic acid (PFOA). Using an electro-oxidation process, you are able to achieve a first order degradation reaction rate constant of 0.02 min. a. How much time is needed to degrade 500 moles of PFOA? b. What would the 1st-order reaction rate constant need to be in order to degrade 500 moles of PFOA in the same solution in 20 minutes?
