A chemical engineer is studying the following reaction: CH 4(9)+2H,S(g) → CS2(9)+4H,(9) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 0.020. The engineer charges ("fills") four reaction vessels with methane and hydrogen sulfide, and lets the reaction begin. She then measures the composition of th 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 CH4 8.25 atm t increase I decrease (no change) H,S 3.44 atm t increase OI decrease (no change) Cs, 2.39 atm t increase I decrease (no change) 2.60 atm t increase I decrease O (no change) CH 8.99 atm t increase I decrease (no change)

Question
A chemical engineer is studying the following reaction: CH 4(9)+2H,S(g) - CS 2(9)+4H2(g) → At the temperature the engineer picks, the equilibrium constant K, for this reaction is 0.020. The engineer charges ("fills") four reaction vessels with methane and hydrogen sulfide, 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 expected change in pressure compound pressure vessel CHA 8.25 atm f increase I decrease (no change) H,S 3.44 atm f increase I decrease (no change) A Cs, f increase I decrease (no change) 2.39 atm H2 2.60 atm f increase I decrease (no change) CHA f increase I decrease (no change) 8.99 atm H,S 4.94 atm f increase I decrease (no change) Cs, I decrease (no change) 1.65 atm f increase H, -0.40 atm f increase I decrease (no change) CH4 8.92 atm f increase I decrease (no change) H,S 4.79 atm f increase I decrease (no change) Cs, 1.72 atm ↑ increase I decrease (no change) H2 -0.11 atm ↑ increase I decrease (no change) B.
