Calculate the entropy change for the isothermal expansion of 3 moles of perfect gas, where the final volume is 5 times greater than the initial. \( \mathrm{R}=8.314 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1} \) Calculate the entropy change for the reverse process. Which of these process is spontaneous according to the second law of thermodynamics?
Expert Answer
The entropy change involved in the isothermal reversible expansion is expressed as: ?S =nRln?(V1V2)or?S=nRln?(P1P2) Where ?S is the change in entropy,
