Calculate the change in entropy for 5 moles of carbon dioxide gas as it is compressed isothermally from 20L to 5L at a temperature of 300K. Consider CO 2 is an (a) ideal gas (b) Van der Waals gas
(a) Show that the entropy change of a Van der Waals gas for an isothermal change V1 to V2 is: ΔS = nR ln (V2 - nb / V1 - nb) (b) Calculate ΔS for expanding on mole of NH3 from 2 dm3 to 20 dm3. Compare this to the ideal gas result. b = 0.0371 dm3/mol
Use the van der Waals equation and the ideal gas equation to calculate the volume of 1.000 mol of neon at a pressure of 500.0 bar and a temperature of 355.0 K. (Hint: One way to solve the van der Waals equation for V is to use successive approximations. Use the ideal gas law to get a preliminary estimate for V ITS 500BAR use bar please not ATM
Initially, at a temperature T, and a molar volume vi, a van der Waals gas undergoes a change of state to the final temperature T2 and the molar volume V2.
