1) Consider the equilibrium: O3 (g) === O2 (g). Calculate the value of Keq, if at equilibrium the amounts of O2 and O3 in a 2-liter flask are 5.24 g and 1.72 g, respectively.
2) A quantity of HBr is placed in a 1-liter container and allowed to come to equilibrium at 450°C. What are the concentrations of H2 and Br2 in equilibrium with 0.4 mole/L of HBr if Keq is 40.5 at 450°C?
H2 (g) + Br2(g) ===== HBr (g)
3) For the chemical equilibrium A + 2B ==== 2C, the value of the equilibrium constant, Kc, is 10. What is the value of the equilibrium constant for the reaction written in reverse?
2C === A + 2B
