Answer the following questions and show your work. 1. In an equilibrium process, C2H4 is reacted with hydrogen gas to produce ethane, C2H6. At a given temperature, the Keq value is 1.04 for the following reaction; C2H4 + H2 →→ C2H6 Initially, 0.34 mol C2H4 and 0.53 mol H2 are placed in a 1.00 L container and equilibrium is established. Determine the equilibrium concentration of each gas in the container. 2. Nitrogen dioxide can break down into nitrogen monoxide and oxygen. The equilibrium constant for this reaction is Kc-0.40. If the equilibrium concentration of NO2 is 0.20 mol/L and the equilibrium concentration of NO (g) is 1.0 mol/L, what is the equilibrium concentration of O2 (g) ?

Because carbonic acid undergoes a second ionization, the student in Exercise 12.39 is concerned that the hydrogen ion concentration she calculated is not correct. She looks up the equilibrium constant for the reaction HCO,-(aq) «=* H+(aq) + COf'(aq) Upon finding that the equilibrium constant for this reaction is 4.8 X 10“H, she decides that her answer in Exercise 12.39 is correct. Explain her reasoning. A student is simulating the carbonic acid—hydrogen carbonate equilibrium in a lake: H,CO,(aq) 5=6 H+(aq) + HCO,'(aq) K = 4.4 X 10'7She starts with 0.1000 A1 carbonic acid.
