The decomposition of nitrogen pentoxide in the reaction 2N2O5(s)4NO2(g)+O2(g) is endothermic with H = +110 kJ/mol. Even so, this reaction is spontaneous for temperatures above
The decomposition of nitrogen pentoxide in the reaction 2N2O5(s)4NO2(g)+O2(g) is endothermic with H = +110 kJ/mol. Even so, this reaction is spontaneous for temperatures above 230 K because the change of a solid into a gas is a large increase of entropy.
a) What is S in J/molK for this reaction?
b) What is G in kJ/mol at 15C?
