Part A It is possible to predict the equilibrium constant of a reaction by combining two or more reactions for which the value of K is known. When combining equilibrium constants, it is important to note the following: Determine the value of the equilibrium constant, Kpal, for the reaction • When a reaction is reversed, its K value is inverted; that is, Kreverse = 1/Kforward- • When the coefficients of a reaction are multiplied by a factor, the K value is raised to the power of that factor. • When reactions are added, their K values are multiplied.

KINETICS AND EQUILIBRIUM Using an equilibrium constant to predict the direction of... A chemical engineer is studying the following reaction: 4 HC1(g) + O₂(g) → 2 H₂O(g) + 2Cl₂(g) At the temperature the engineer picks, the equilibrium constant K for this reaction is 0.31. The engineer charges ("fills") four reaction vessels with hydrogen chloride and oxygen, 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 A B с compound HC1 0₂ H₂O Cl₂ HCI 0₂ H₂O Cl₂ HCI 0₂ H₂O C1₂ pressure 5.09 atm 5.63 atm 3.31 atm 4.48 atm 3.91 atm 5.34 atm 3.90 atm 5.07 atm 2.74 atm 5.05 atm 4.48 atm 5.65 atm expected change in pressure O ↑ increase ↑ increase O ↑ increase O ↑ increase O ↑ increase ↑ increase ↑ increase O ↑ increase ↑ increase O ↑ increase ↑ increase ↑…
