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

For the process

\[ 1 \mathrm{Ar}(300 \mathrm{K}, 1 \text { bar }) \longrightarrow 1 \mathrm{Ar}(200 \mathrm{K}, 10 \mathrm{bar}) \]

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

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

(b)$+27.57 \mathrm{JK}^{-1} \mathrm{mol}^{-1}$

(c)$-24.20 \mathrm{JK}^{-1} \mathrm{mol}^{-1}$

(d)$+24.20 \mathrm{JK}^{-1} \mathrm{mol}^{-1}$
