The research and development unit of a chemical company is studying the reaction of CH₄ and H₂S, two components of natural gas. In one experiment, 1.00 mol of CH₄, 1.00 mol of CS₂, 2.00 mol of H₂S, and 2.00 mole of H₂ are mixed in a 250 mL vessel at 960C. If [CH₄] = 5.56 M at equilibrium, what are the equilibrium concentrations of the other substances?
