The research and development unit of a chemical company is studying the reaction of CH4 and H2S, two components of natural gas:
CH4(g) + 2H2S(g) ⇌ CS2(g) + 4H2(g)
In one experiment, 1.00 mol of CH4, 1.00 mol of CS2, 2.00 mol of H2S, and 2.00 mol of H2 are mixed in a 250-mL vessel at 960 oC. At this temperature, Kc = 0.036. If [CH4] = 5.56 M at equilibrium, what are the equilibrium concentrations of H2?
A) 5.56 M B) 1.76 M C) 6.44 M D) 2.44 M
