Question

What is ΔG° at 298 K for the following reaction? H₂(g)+ Br₂(g)→ 2HBr(g); ΔH° = -103.8 kJ; ΔS° = 21.3 J/K at 298 K

Quizplus · Accepted Answer

ΔG° = ΔH° - TΔS°
ΔG° = (-103.8 kJ) - (298 K)(21.3 J/K)(1 kJ/1000 J)
ΔG° = -110.1 kJ
Therefore, the best choice is C as it is the closest option to -110.1 kJ.
