Q84 · CSIR-NET Chemistry, December 2017

Paper: CSIR-NET December 2017 · Subject: Physical Chemistry · Chapter: Thermodynamics · Topic: Thermodynamics – General · Marks: 2 · Difficulty: Medium

One mole of an ideal gas undergoes a cyclic process (ABCDA) starting from point A through 4 reversible steps as shown in the figure. Total work done in the process is
(a)$\mathrm{R}\left(\mathrm{T}_{1}-\mathrm{T}_{2}\right) \frac{\mathrm{V}_{2}}{\mathrm{V}_{1}}$
(b)$\mathrm{R}\left(\mathrm{T}_{1}+\mathrm{T}_{2}\right) \frac{\mathrm{V}_{2}}{\mathrm{V}_{1}}$
(c)$\mathrm{R}\left(\mathrm{T}_{1}+\mathrm{T}_{2}\right) \ln \frac{\mathrm{V}_{2}}{\mathrm{V}_{1}}$
(d)$\mathrm{R}\left(\mathrm{T}_{1}-\mathrm{T}_{2}\right) \ln \frac{\mathrm{V}_{2}}{\mathrm{V}_{1}}$
