Chapter 14.6, Problem 2E

Determine the equilibrium constant at T = 298.15 K for each of the following reactions:

1. A. Formation of ethanol from ethylene and water:

   C₂H₄(g) + H₂O(g) ↔ C₂H₅OH(g)

2. B. Dehydrogenation of cyclohexane to form benzene:

   C₆H₁₂(g) ↔ C₆H₆(g) + 3H₂(g)

3. C. Combustion of methane:

   CH₄(g) + 2O₂(g) ↔ CO₂(g) + 2H₂O(g)

14-2. For each of the three reactions listed in Exercise 14-1, use the shortcut van ’t Hoff equation to compute the equilibrium constant at T = 500 K.
