Extent of Reaction for Material Balances

[SmugMess]

9 hours in class on this and this video taught me more in 8 minutes. Super good video!

This screencast has been reviewed by faculty from other academic institutions.

I missed this stuff...i wish all mass balance questions were this easy. Extent of reaction approach is definitely easier than the black box.

thank you for all your work. These videos are helping me a great deal.

Your vids helps me alot for my assignment😭😭😭. Thank you

This is Perfect and straight to the point...thank you♡

hi, if theres a recycle stream will na0 be the fresh feed or the amt entering reactor ie including recycle

My textbook, "Elementary Principles of Chemical Processes, 4th edition, Felder"
indicates that the extent of reaction is dimensionless. My professor along with class thought this must of been a mistake, but he contacted the author, and was convinced that it is in fact, dimensionless. Will it mess me up to assume that there is a unit? I don't see why it would be unitless, because saying the extent of reaction is 30, doesn't really tell us anything

why is initial C2H4 canceled out from the second equation? I dont understand that.

[hiei]

Can you use the same equation for mass flow?

I'd like to know why we cant just simply do this: There's 5 moles of ethylene forming for every mole of propylene. We know that a total of 70 moles of ethane reacts. So we can just do 5/6 x 70 = moles of ethylene formed and 1/6 x 70 for the moles of propylene formed?

Hey, how you see that the extent of reaction 1 is 6 times exent reaction of 2? How do you find £1? I dont understand how you go from S=£1-£2/£2 to £1=6£2
