A chemical engineer is studying the following reaction: H₂(g) +1₂(g) → 2 HI(g) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 0.94. The engineer charges ("fills") three reaction vessels with hydrogen and lodine, 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 H₂ HI H₂ 42 HI # EF HI pressure 1.79 atm 1,36 atm 1.51 atm 2.49 atm 1.89 alm 2.10 atm 1.52 atm 1.09 atm 2.06 atm expected change in pressure Ot increase O decrease O increase O decrease O increase O O1 increase O decrease decrease decrease decrease 1 increase O O increase O OT increase O decrease 01 increase O decrease Tincrease O decrease X (no change) (no change) (no change) (no change) (no change) (no change) (no change) (no change) (no change)
