Question

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

Quizplus · Accepted Answer

The decomposition of a compound into its constituent elements is an endothermic process, meaning it requires energy, so the ΔH° value should be positive.
