Calculate ΔG° for the Reaction Below and Tell Whether It

question 103

Multiple Choice

Calculate ΔG° for the reaction below and tell whether it is spontaneous or nonspontaneous under standard conditions at 25°C. 2 S (s) + 3 O₂ (g) + 2 H₂O (l) → 2 H₂SO₄ (l) ΔH° = -1056 kJ/mol
ΔS° = -505 J/mol

• A)ΔG° = -1207 kJ and the process is spontaneous.
• B)ΔG° = -1207 kJ and the process is nonspontaneous.
• C)ΔG° = -906 kJ and the process is spontaneous.
• D)ΔG° = -906 kJ and the process is nonspontaneous.
