Question

Multiple choice) At 298K, the equilibrium constant for this reaction: H2(g) + 1/2 O2 (g) <--> H2O (l)

(Delta Gf for H2O (l) is -237 and H2O (g) is -229.)

1) has a value of 1.0 at equilibrium

2) is larger than the Keq for H2 (g) + 1/2 O2 (g) <--> H2O (g)

3) cannot be computed since data on O2 and H2 are not provided

4) will have the same value as the Keq for H2 (g) + 1/2 O2 (g) <--> H2O (g)
