Intro to Chemical Equilibrium
Multiple Choice
Multiple ChoiceMethane (CH4) reacts with hydrogen sulfide to yield hydrogen gas and carbon disulfide, a solvent used in the manufacturing rayon and cellophane. What is the value of Kc at 1000 K if the partial pressures in an equilibrium mixture at 1000 K are 0.20 atm methane, 0.15 atm hydrogen sulfide, 0.30 atm carbon disulfide and 0.10 atm hydrogen gas?
CH4 (g) + 2 H2S (g) ⇌ 4 H2 (g) + CS2 (g)
