when we are asked to calculate the standard reaction S/H/G, does the stoichiometric coefficient of one product must be 1? Or we can calculate these standard reaction entropy/enthalpy/ free energy just by balancing the reaction regardless of the product's stoichiometric coefficient ? Since in 9.59, the stoichiometric coefficients for products are not 1 but in 9.57 they are 1. Can somebody help me with this? Thanks!
I believe that you should work with the balanced equations! For both 9.57 and 9.59, the equations they gave are already balanced so you can go ahead and work with those. For these problems just remember that the ΔHf and ΔGf of O2 are 0. Hope this helps!
