2 H₂S(9)+30₂(g) → 2 SO₂(g) + 2H₂O(g) At the temperature the engineer picks, the equilibrium constant K for this reaction is 6.6. The engineer charges ("fills") four reaction vessels with hydrogen sulfide and oxygen, and lets the reaction begin. She then measures the composition of the mixture inside each vessel from time to time. Her first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should expect next time she measures the compositions. reaction vessel compound pressure expected change in pressure H₂S 6.03 atm decrease (no change) 0₂ O decrease (no change) 3.82 m 10.81 m So, (no change) decrease decrease H₂O 10.66 atm (no change) H₂S 6:18 am (no change) 0₂ 4.47 atm (no change) (no change) so, 9,07 atm i decrease decrease decrease decrease decrease decrease H₂O 8.94 atm (no change) H₂S 4.90 atm (no change) (no change) 0₂ 2.55 atm 10.35 atm decrease So, (no change) decrease (no change) 11,0 10:22 am C increase OT increase 1 increase OT increase Ot increase Ot increase Ot increase t increase O increase increase 1 increase 1 increase
