Question
(Q77) The standard Gibbs free energy (AG°rxn) for the formation of sulfur trioxide from sulfur
dioxide and oxygen gas is -72.3 kJ/mol. The balanced chemical equation is SO2 (g) + ½ O2 (g)
-->
SO3 (g).
What will be the Gibbs Free energy of the reaction (in kJ/mol) if it takes place at a low temperature
of -13.7 and the concentrations of three gases are:
SO2 = 0.112 M
%3D
O2 = 0.110 M
SO3 = 1.74 M
