Question
2 moles of an ideal gas undergo isothermal reversible expansion at 300 K from volume V1 to 3V1. Using R = 8.314 J/mol/K, calculate the entropy change of the gas in J/K, rounded to 4 decimal places.
✓ Verified answer: 18.2677checked by our engine — not a guess
Step-by-step solution
For isothermal reversible expansion of an ideal gas, dS = nR ln(V2/V1) = 2 * 8.314 * ln(3) = 16.628 * 1.0986 = 18.2677 J/K. Final answer: 18.2677
