Quiz #6 Incomplete combus.on of methane leads to the following (unbalanced) reac.on: CH 4 + O 2 à CO + H 2 O Calculate: I. If methane is fed at a rate of 40.0 kmol CH 4 /h, what oxygen feed rate (kmol/h) would correspond to 25% molar excess of O 2 ? II. If 320 kg of methane and 400 kg of oxygen are fed to a batch reactor, determine the kmol of CO produced if the reac.on proceeds to comple.on. Hint: MW of CH 4 is 16, MW of O 2 is 32 a) 50 kmol/h, 8.3 kmol b) 75 kmol/h, 8.3 kmol c) 75 kmol/h, 12.5 kmol d) 50 kmol/h, 12.5 kmol Answers (Part I, Part II):

    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.
