Q68 · CSIR-NET Chemistry, December 2018
Paper: CSIR-NET December 2018 · Subject: Physical Chemistry · Chapter: Thermodynamics · Topic: Laws State Functions · Marks: 2 · Difficulty: Medium
Consider a phase transition between two incompressible phases. The correct statement among the following is
(a)The transition is independent of pressure
(b)The transition is independent of temperature
(c)The entropy of such transition is always zero
(d)The enthalpy of such transition is always non-zero
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
With ΔV = 0 the Clapeyron slope dp/dT = ΔS/ΔV is infinite: the transition temperature does not change with pressure.
