Chemistry - Thermodynamics - II Question with Solution | TestHub

One mole of an ideal gas is expanded isothermally and reversibly to half of its initial pressure. $\Delta S$ for the process in $\mathrm{J}{\mathrm{K}}^{-1}{\mathrm{mol}}^{-1}$ is $[\ln 2=0.693$ and $R=8.314,\mathrm{J}/(\mathrm{mol}\mathrm{K})]$
