Hydrogen sulfide is removed from natural gas through a “sweetening process” as it is toxic and its combustion produces corrosive substances. A proposed process is given below:

2H2S(g) + SO2(g) --> 3S(s) + 2H2O(g)

In a test process, a gas stream which contains 20.0% H2S and 80.0% CH4 was combined with a stream of pure SO2 prior to entering the reactor. The process produced 5000 lb of solid S, and in the product gas, the ratio of SO2 to H2S was equal to 3.00, and the ratio of H2O to H2S was 10.0. Draw the diagram. Using the extent of reaction balance, determine the following:

a.) limiting reactant (LR)

b.) fractional conversion of the LR

c.) Feed rates of the two input streams

Hydrogen sulfide gas is an extremely toxic (and smelly) gas that can form from anaerobic digestion (e.g. in sewer pipes). The ΔGf° of H2S (g) and H2S (aq) are -33.4 kJ/mol and -27.87 kJ/mol, respectively so that KH = 9.32 atm/(mole/L) at 25 C. At concentrations above 0.01 ppm in the air, the rotten egg smell is first noticeable. At concentrations above 2 ppm, the gas becomes toxic. Calculate the pH of water in equilibrium with H2S at 0.01 ppm...
