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 0.67. The engineer charges ("fills") three reaction vessels with hydrogen and chlorine, and lets the reaction begin. She then measures the composition of the mixtur 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 A B С compound CL HC1 C1₂ HC1 C1₂ HCI pressure 2.46 am 4.94 atm 1.73 atm 1.68 atm 4.16 atm 3.31 atm 2.07 atm 4.55 atm 2.52 atm expected change in pressure O ↓ decrease O↓ decrease O ↓ decrease O ↑ increase O ↑ increase O ↑ increase O ↑ increase O ↑ increase O ↑ increase O ↑ increase O ↑ increase O ↑ increase ↓ decrease O↓ decrease decrease ↓ decrease decrease decrease O (no change) O (no change) O (no change) (no change) O (no change) (no change) (no change) (no change) O (no change)
