The phase diagram for sulfur is given below.  At 424 K and 1300 atm,

Quizplus · Accepted Answer

According to the phase diagram, at 424 K and 1300 atm, the point falls on the line between the solid phase of rhombic sulfur and liquid sulfur phase. This means that both rhombic and liquid sulfur are in equilibrium. Additionally, the line separates the rhombic and monoclinic sulfur solid phases, indicating that both solid phases are present as well. Therefore, the correct answer is (C) rhombic sulfur, monoclinic sulfur, and liquid sulfur exist in equilibrium.
