Hi all, having a bit of trouble with the following. Please explain the answer so that I can understand it, not just have the right answer. Thanks!

CO & H2 are fed to a reactor operating @ steady state. There are no other components in the feed. The product stream contains unreacted CO & H2, along with CH3OH, C2H5OH, and C3H7OH, and CO2. The feed rates of CO & H2 to the reactor are 100 mol/h each, and the rates in the stream that leaves the reactor (in mols/hr) are H2-30, CO-30, and C2H5OH-5.

What is the mole fraction of each species in the product stream?

This looks like your assignment, can you post your answer then explain it for us...

1.do your mass balance
CO+2H2=CH3OH
2CO+3H2=C2H5OH
3CO+4H2=C3H7OH

2.determine the amount of carbon for methanol and propanol in the exit stream

3.determine the amount of carbon dioxide at exit stream, do your elemental carbon balance
amount of carbon in=amount of carbon out

3.the total moles out is the summation of all the molar amount of each compound in the exit streams

4. determine the molar fraction of each component by dividing each component by the total moles
