Ethyl butyrate (artificial pineapple flavoring) can be synthesized via acid-catalyzed Fischer Esterification by refluxing equimolar amounts of butyric acid and ethanol with a catalytic amount of concentrated sulfuric acid (H2SO4) as shown. a. Under the conditions above, ethyl butyrate is produced in 70% yield once equilibrium is established. Describe two different ways to increase the yield of ester above 70%. [4 pts; 2 pts each] Way \#1: Way \#2: b. Describe a method that could be used to monitor the progress of the reaction while it is running. For full credit, describe briefly how you would know when the reaction is complete by that method. What evidence would you look for
