(choose chapter or problem)

Use data from Appendix C to calculate the equilibrium constant, K, and \(\Delta G^{\circ}\) at 298 K for each of the following reactions:

(a) \(\mathrm{H}_{2}(g)+\mathrm{I}_{2}(g) \rightleftharpoons 2 \mathrm{HI}(g)\)

(b) \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(g) \rightleftharpoons \mathrm{C}_{2} \mathrm{H}_{4}(g)+\mathrm{H}_{2} \mathrm{O}(g)\)

(c) \(3 \mathrm{C}_{2} \mathrm{H}_{2}(g) \rightleftharpoons \mathrm{C}_{6} \mathrm{H}_{6}(g)\)

Delta G^circ

H2(g) + I2(g) rightleftharpoons 2 HI(g)

C2H5OH(g) \rightleftharpoons C2H4(g) + H2O(g)

3 C2H2(g) \rightleftharpoons C6H6(g)
