Q.
The second law of thermodynamics is a fundamental law of science. In this problem, we consider the thermodynamics of an ideal gas, phase transition, and chemical equilibrium. Three moles of CO2 gas expands isothermally (in thermal contact with the surroundings; temperature = 15.0°C) against volume fixed external pressure of 1.00 bar. The initial and final volume of the gas are 10.0 L and 30.0 L, respectively.Select the correct order of the entropy change. Assuming CO2 to be an ideal gas, ∆sys S is Δsurr S is

Detailed Solution
In expansion of CO, gas molecule, entropy of system Δsys S increases or Δsys S>0 and entropy of surrounding decreases Δsurr S<0. - Work done =q=nRT lnV2V1=3×8.314×288.15×ln3010∴ΔS=qT or Δsys S=3×8.314×288.15×ln3010288.15=27.4JK−1.entropy of surroundings should be less than zero
