1.)Hydrogen sulfide, a colorless gas with a foul odor, dissociates on heating: 2H2S(g) 2H2(g)+ S2(g) When 0.100 mol H2S was put into a 10.0-L vessel and heated to 1132°C, it gave an equilibrium mixture containing 0.0285 mol H2. What is the value of Kc at this temperature? 2.) In the contact process, sulfuric acid is manufactured by first oxidizing SO2 to SO, which is then reacted with water. The reaction of SO2 with 02 is 2SO2(g)+ O2(g) 2S03(g) A 2.000-L flask was filled with 0.0400 mol SO2 and 0.0200 mol O2. At equilibrium at 900 K, the flask contained 0.0296 mol SO3. How many moles of each substance were in the flask at equilibrium? What is the value of Kc at this temperature?
