A chemical engineer is studying the following reaction: H₂(g) + Cl₂(g) → 2 HCl (g) At the temperature the engineer picks, the equilibrium constant K for this reaction is 0.39. The engineer charges ("fills") three reaction vessels with hydrogen and chlorine, 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 are shown in the table below. Predict the changes in the compositions the engineer should expect next time he measures the compositions. reaction vessel A B с compound H₂ Cl₂ H Cl H₂ Cl₂ H CI H₂ Cl₂ H Cl pressure 2.00 atm 2.71 atm 2.34 atm. 2.70 atm 3.41 atm 0.93 atm 2.66 atm 3.37 atm 1.00 atm expected change in pressure ↑ increase Ot increase ↑ increase Ot increase Ot increase ↑ increase Ot increase Ot increase Ot increase O decrease ↓ O↓ decrease O decrease Odecrease O decrease O decrease O decrease Odecrease Odecrease O(no change) (no change) O (no change) (no change) O(no change) O(no change) O(no change) O (no change) O (no change)
