Ethylene oxide production, steady state rate

Structural Sensitivity. Figure 1 shows the steady-state rates of ethylene oxide (EtO) and CO2 production as a function of temperature, in Arrhenius form, at an ethylene pressure (P-.) of 20 torr and P. 

Figure 6.4. Examples for the four types of global classical promotion behaviour. Work function increases with the x-axis. (a) Steady-state (low conversion) rates of ethylene oxide (EtO) and C02 production from a mixture of 20 torr of ethylene and 150 torr of 02 for various Cs predosed coverages on Ag(lll) at 563 K19 (b) Rate of water-gas shift reaction over Cu(l 11) as a function of sulphur coverage at 612 K, 26 Torr CO and 10 Torr H202° (c) Effect of sodium loading on NO reduction to N2 by C3H6 on Pd supported on YSZ21 at T=380°C (d) Effect of sodium loading on the rate of NO reduction by CO on Na-promoted 0.5 wt% Rh supported on Ti02(4% W03).22...

The nitrogen assumes cationic properties and forms a complex with the dye anion. The non-ionic ethylene oxide condensate portion of the molecule keeps the addition product in a state of solution. The wool has no affinity for the dye anion which is comple.xed with the nitrogen atom at low temperatures. As the liquor becomes hotter the dye anions are gradually released. Not only does it follow that the dye becomes available at a steady and slow rate, but also the release takes place at higher temperatures when the fibre is more swollen and the dye aggregates are broken down. 

A gaseous stream consisting of 60% C2H4, 30% O2, and 10% N2 (by mole) is fed at a rate of 40 mol/min into a flow reactor operating at steady state. If the mole firaction of oxygen in the reactor effluent stream is 0.08, calculate the production rate of ethylene oxide.
