Chemical Engineering Thermodynamics

Which of the following decreases with increase in pressure?

  • A. Melting point of ice
  • B. Melting point of wax
  • C. Boiling point of liquids
  • D. None of these
Answer: Option A.

According to Le Chatlier’s principle the system will react in such a way that it minimizes the effect of deviation from equilibrium. Since, ice has the more volume than water Equilibrium shifts towards water (less volume) side thereby, minimizing the effect of pressure and regaining a new equilibrium. So, we can say the melting point is reached fast or decreased.
