Calculate the Keq for the fo llowing react ion based on concentrations of PCl5 = 0.030 M, PCl3 = 0.97 M and Cl2 = 0.97 M at 300 °C. ˆˆ
PCl5 (g) ‡ˆ† PCl3 (g) + Cl2 (g) Keq = 10 Chemistry 52 Chapter 16 Examples: 2. What is the Keq for the fo llowing equilibrium at 1000 °C ˆˆ
CO (g) + 3 H2 (g) ‡ˆ† CH4 (g) + H2O (g) if [H2] = 0.30 M, [CO] = 0.51 M, [CH4] = 1.8 M, and [H2O] = 2.0 M 3. The equilibrium shown below has a constant Keq = 5.0. If at equilibrium the concentration of Cl2 is 0.25 M and COCl2 is 0.80 M, what is the equilibrium concentration of CO? ˆˆ
CO (g) + Cl2 (g) ‡ˆ† COCl2 (g) 4. The equilibrium constant, Keq, for the reaction shown below is 54 at 425 °C. If the equilibrium mixture contains 0.030 M HI and 0.015 M I2, what is the equilibrium concentration of H2? ˆ ˆˆ
