Applied Exercises 8.111

Postby Semi Yoon » Tue Jan 29, 2019 6:30 pm

Crude petroleum is often contaminated by poisonous hydrogen sulfide gas. The Claus process for the extraction of sulfur from petroleum has two steps:

2 H2S(g) + 3 O2(g) ---> 2 SO2(g) + 2 H2O(l)
2 H2S(g) + SO2(g) ---> 3 S(s) + 2 H2O(l)

How would you write a thermochemical equation for the overall reaction that does not contain SO2? What would the equation look like?

You would multiply all of the mole ratios of the second reaction by 2, and then add both reactions, which would cancel out the SO2 term.
