Question

a) Calculate ΔS, ΔStot, and ΔSsur when the volume of 140 g of CO initially at 273 K and 1.00 bar increases by a factor of three in an adiabatic reversible expansion. Take CP,m to be constant at the value 29.14 J⋅mol^−1⋅K^−1 and assume ideal gas behavior. The temperature of the surroundings is 273 K. Express your answers in joules per kelvin to three significant figures separated by commas. b) Calculate ΔS, ΔStot, and ΔSsur when the volume of 140 g of CO initially at 273 K and 1.00 bar increases by a factor of three in an expansion against Pext=0. Take CP,m to be constant at the value 29.14 J⋅mol^−1⋅K^−1 and assume ideal gas behavior. The temperature of the surroundings is 273 K. Express your answers in joules per kelvin to three significant figures separated by commas. c) Calculate ΔS, ΔStot, and ΔSsur when the volume of 140 g of CO initially at 273 K and 1.00 bar increases by a factor of three in an isothermal reversible expansion. Take CP,m to be constant at the value 29.14 J⋅mol^−1⋅K^−1 and assume ideal gas behavior. The temperature of the surroundings is 273 K. Express your answers in joules per kelvin to three significant figures separated by commas.
