One hundred cubic meters of carbon dioxide initially at 150 degrees Celsius and 50 bar is to be isothermally compressed in a frictionless piston-and-cylinder device to a final pressure of 300 bar. Assume that this is a reversible process. a.) Use the ideal gas equation of state to calculate: i. The volume of the compressed gas ii. The work done to compress the gas iii. The heat flow on compression b.) Use the van der Waals equation of state to...
(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
(1) Using the data found in BOB, calculate the pressure exerted by 2.500 moles of carbon dioxide confined in a volume of 1.000 L at 450K assuming that it obeys (a) the ideal gas equation of state, and (b) the van der Waals equation of state.
According to the ideal gas law, a 0.9832 mol sample of carbon dioxide gas in a 1.975 L container at 271.4 K should exert a pressure of 11.09 atm. By what percent does the pressure calculated using the van der Waals' equation differ from the ideal pressure? For CO2 gas, a = 3.592 L'atm/mol and b=4.267x102 L/mol. Hint: % difference = 100*(P ideal - Pvan der Waals)/P ideal
a). In the ideal gas mixture, is there any way the process entropy change equals zero? b) Calculate μ, the Joule-Kelvin coefficient for a Van der Waals gas.
¨Calculate the entropy change when 2 moles of an ideal gas are allowed to expand isothermally from an initial volume of 1.5 L to 2.4 L. Then estimate the probability that the gas will contract spontaneously from the final volume to the initial one.
According to the ideal gas law, a 1.003 mol sample of carbon dioxide gas in a 1.561 L container at 270.6 K should exert a pressure of 14.27 atm. What is the percent difference between the pressure calculated using the van der Waals' equation and the ideal pressure? For CO2 gas, a = 3.592 L'atm/mol2 and b = 4.267x10-2 L/mol.
