A 127.39 kmol/hr gas mixture containing carbon monoxide and hydrogen reacts catalytically to produce methanol: CO+ 2H₂ --> CH₃OH



The fresh feed contains stoichiometric amount of carbon monoxide and hydrogen but contains a small percentage of inert gases. A condenser separates the unreacted gases and inert (argon) from the product where a part of the gas stream is recycled back into the main feed line to the reactor and the rest is purged. Assume 100% overall conversion. If the process purges 12.83 mol/hr of argon, what is the percentage of argon in the fresh feed?

a. 0.0010

b. 0.0101

c. 10.0714
