The value of ΔS° for the formation of POCl₃ from its constituent elements, P₂(g) + O₂ (g) + 3Cl₂ (g) → 2POCl₃ (g)
Is ________ J/K ∙ mol.

Question

The value of ΔS° for the formation of POCl₃ from its constituent elements, P₂(g)+ O₂ (g)+ 3Cl₂ (g)→ 2POCl₃ (g) Is ________ J/K ∙ mol.

Quizplus · Accepted Answer

The correct answer is A because the entropy change for the formation of POCl3 from its constituent elements is negative. This is because the number of moles of gas decreases from 5 to 2, and the entropy of a gas is proportional to the number of moles.
