Question
Use data from Appendix IIB to calculate the equilibrium constant at 25 C for each reaction.a. 2 CO(g) + O2(g)2 CO2(g)b. 2 H2S(g)2 H2(g) + S2(g)
Step 1
This is given by the difference in the standard Gibbs free energies of formation (ΔfG°) of the products and the reactants. For reaction a, the standard Gibbs free energy change is given by: ΔG° = 2ΔfG°(CO2) - 2ΔfG°(CO) - ΔfG°(O2) For reaction b, the standard Show more…
