Answer to Question #108775 in General Chemistry for Alissa Carpenter

Question

Using standard thermodynamic data (i.e., standard Gibbs free energy of formation, ∆Gf°), calculate the standard Gibbs free energy change, ΔG°, of the following reaction and select the correct statement:

S(s) + O2(g) → SO2(g)




ΔG° = – 300.4 kJ; the reaction is at equilibrium.


ΔG° = – 300.4 kJ; the reaction is non-spontaneous.




ΔG° = 300.4 kJ; the reaction is spontaneous.


ΔG° = – 300.4 kJ; the reaction is spontaneous.

Answer 1

ΔG° = – 300.4 kJ; the reaction is at equilibrium.
