Using an equilibrium constant to predict the direction of spontaneous...A chemical engineer is studying the following reaction:H2(g)+I2(g) →2 HI(g)Press (fn) F to exit full screen1/3At the temperature the engineer picks, the equilibrium constant ✓ for this reaction is 0.50.РThe engineer charges ("fills") three reaction vessels with hydrogen and iodine, and lets the reaction begin. He then measures the composition of the mixtureinside 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.reactionvesselcompoundpressureexpected change in pressureH23.13 atm↑ increase↓ decrease(no change)A123.72 atm↑ increase↓ decrease(no change)HI1.26 atm↑ increase↓ decrease(no change)H22.22 atm↑ increase↓ decrease(no change)BI,2.81 atm↑ increase↓ decrease(no change)HI3.06 atm↑ increase↓ decrease(no change)H₁2.70 atm↑ increase↓ decrease(no change)C123.29 atm↑ increase↓ decrease(no change)HI2.11 atm↑ increase↓ decrease(no change)
