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

Write a thermochemical equation for the overall reaction that does not contain SO₂.

(b) What enthalpy change would be associated with the production of 60.0 kg of sulfur?

(c) Would the reactor need to be cooled or heated to maintain a constant temperature?
