H 2 O 2 C 14 H 10 O 4 dye CO2 C 6 H 6 O dye You have been hired by a nightclub to design a glowing ring that will line run along the perimeter of the room. The owner really wanted to use glow sticks, but you don't want to have to change them every 30 mins when they burn out. Instead you desing a flowing system, using the same chemistry as the glow sticks. The system will make one loop around the ceiling of the 5m x 5m room, entering and exiting at nearly the same point. Your flowing channel is 1 cm in diamter. The system diagram and chemical formula are shown below. The phenyl oxalate ester (C 14 H 10 O 4 ) flows in at 5E-3 mol/min. It reacts with hydrogen peroxide (H 2 O 2 ) to excite a dye. Assume instantaneous even mixing at entry and no mixing after that point. What molarity of phenyl oxalate ester will keep the room glowing? What is thew molarity of the other components? C 14 H 10 O 4 + H 2 O 2 CO 2 + C 6 H 6 O Known C 14 H 10 O 4 molar flow rate = 5E-3 mol/min Dimentions of flowing channel = 20m long, 0.01m in diameter Reaction only lasts 30 mins Solution Write the mass balance equations a C 14 H 10

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
