10 kJ of heat is absorbed by a gas dissociation reaction occurring reversibly and isothermally at 300
K in an elastic balloon. The gas mixture expands producing 5 kJ of work against the tension of the
balloon and the pressure of the atmosphere. Calculate the change in entropy of the gas mixture in the
balloon and the change in entropy of the universe

Three moles of an ideal gas expand isothermally and reversibly
from 90 to 300 L at 300 K.
a) Calculate ΔUm, ΔSm, w per mole, and q per mole.
b) If the expansion is carried out irreversibly by allowing the
gas to expand rapidly into a vacuum, determine ΔUm, ΔSm, w per
mole, and q per mole
