To be in thermodynamic equilibrium a system must be in chemical equilibrium, in a steady state
and in a uniform state. Uniformity implies that there are no gradients ...
Methods of Finding DeltaG and K (Gibb's Free Energy and Equilibrium Constant) from Standard Tabulated Thermodynamic Quantities.
Write the equilibrium -constant expression and calculate the value of the equilibrium constant for each of the follow reactions at 298 K, using data from Appendix C. ** Appendix C is in the Chemistry: The Central Science 11e textbook. It is a chemistry 100 (first year book). The Appendix contains delta Hf, delta Gf and S at 298.15K for selected substances.

b) C2H5OH (g) <--> C2H4 (g) + H2O (g)
c) 3 C2H2 (g) <-> C6H6 (g)
