Subject: Physical Chemistry · Chapter: Thermodynamics · Topic: Laws State Functions · Exam: GATE 2005-2021 · Marks: 2 · Difficulty: Medium

For the process

$1\,\mathrm{Ar}(300\,\mathrm{K}, 1\,\mathrm{bar}) \longrightarrow 1\,\mathrm{Ar}(200\,\mathrm{K}, 10\,\mathrm{bar})$

assuming ideal gas behavior, the change in molar entropy is:

(a)$-27.57\ \mathrm{J\,K^{-1}\,mol^{-1}}$

(b)$+27.57\ \mathrm{J\,K^{-1}\,mol^{-1}}$

(c)$-24.20\ \mathrm{J\,K^{-1}\,mol^{-1}}$

(d)$+24.20\ \mathrm{J\,K^{-1}\,mol^{-1}}$
