I need the process, thank you.

Two common waste products in many oil refineries are hydrogen sulfide (H2S) and sulfur dioxide (SO2), and the following reaction suggests a way to get rid of both at the same time: 2H2S(g) + SO2(g) 3S(s) + 2H2O Assuming a stoichiometric mixture of H2S and SO2 that attains equilibrium at 450◦C and 8 bar, what is the final mole fraction of water yH2O?

6. Two common waste products in many oil refineries are hydrogen sulfide (H28) and sulfur
dioxide (802), and the following reaction suggests a way to get rid of both at the same time: 2HQS(g) + 802(9) : 38(3) + 2-20 Assuming a stoichiometric mixture of H28 and 802 that attains equilibrium at 450°C and 8
bar, what is the final mole fraction of water yHgo?
The following data are available: Species AfH" (1/ mol) AfG" (I/mol) H28 -20,630 63,560
802 -296,830 -300,194
H20 -241,818 -228,572 You may assume that the standard state heat of reaction is independent of temperature. Ans. yH20 = 0.6.
