Calculate $\Delta$S° for the combustion of propane.

Question

Quizplus · Accepted Answer

The Gibbs free energy change for the combustion of propane is given by:
ΔG° = ΣnΔG°f(products) - ΣnΔG°f(reactants)
We can calculate the ΔG°f values for propane, carbon dioxide, and water from standard data tables. Substituting these values in the above equation and simplifying, we get:
ΔG° = -2043.1 kJ/mol
Using the equation:
ΔG° = ΔH° - TΔS°
where ΔH° is the enthalpy change, ΔS° is the entropy change, and T is the temperature in Kelvin, we can solve for ΔS°, which is the entropy change.
ΔS° = (ΔH° - ΔG°)/T
Substituting the values, we get:
ΔS° = - 100.9 J/K
Therefore, the answer is option D, -100.9 J/K.
