A chemicаl engineer is studying the fоllоwing reаctiоn: CH4(g) + 2H2S(g) → CS2(g) + 4H2(g) At the temperаture the engineer picks, the equilibrium constant, Kp, for this reaction is 31. The engineer fills the reaction vessel with methane and hydrogen sulfide, and lets the reaction begin. He then measures the composition of the mixture inside each vessel from time to time. His first set of measurements show that there are 9.59 atm CH4, 6.70 atm H2S, 7.54 atm CS2, and 8.52 atm H2. Predict the changes in the compositions the engineer should expect next time he measures the compositions. Select all that apply.
