Question

The value of ΔG° at 25 °C for the decomposition of POCl₃ into its constituent elements, 2POCl₃ (g)→ P₂ (g)+ O₂ (g)+ 3Cl₂ (g) Is ________ kJ/mol.

Quizplus · Accepted Answer

The correct answer is B) +1108.7. This is because the decomposition of a compound into its constituent elements typically requires energy, indicating an endothermic reaction. The positive value of ΔG° suggests that the reaction is non-spontaneous under standard conditions at 25 °C.
