1. The problem statement, all variables and given/known data
Ethylene oxide is produced industrially from the reaction of ethylene with oxygen at atmospheric pressure and 283 oC, in the presence of silver catalyst.
C
2H
4 + O
2---> C
2H
4 O
Assuming 100 % yield, how many kg of ethylene oxide can be produced from 35100 L of a mixture containing ethylene and oxygen in 1:1 molar ratio?
The attempt at a solutionFirst I balanced the equation like so,
2 C
2H
4 + O
2---> 2C
2H
4 O
I then converted the temp. from celsius to kelvin so,
525.15K
I'm not sure what value I should use for pressure, in a question like this am I just assuming that P = 1atm?
I then applied PV= nRT and solved for moles. Once I have the number of moles I used the molar mass to get it into grams and then I converted grams to kilograms.
I still got the answer wrong however.
What am I doing wrong?
Also, what value for the gas constant do I use that will work with the units K, mol, atm, and L?
