A tank containing carbon dioxide at 400K and 50 bar is vented until the temperature in the tank falls to 300K. Assuming there is no heat transfer between the gas and the tank, find the pressure in the tank at the end of the venting process and the fraction of the initial mass of gas remaining in the tank for each of the following cases. a) the equation of state of carbon dioxide is P(V_mol-b)=R*T. b) Carbon dioxide obeys the law of corresponding states. c) Carbon dioxide obeys the Peng-Robinson equation of state

A 0.2m3 rigid tank initially contains pure oxygen gas (02) at 20°C and 1000 kPa. The tank containing the oxygen is put on a scale to measure its mass. The initial mass is recorded as 110.4 kg. Nitrogen gas is injected isothermally into the tank until the scale reads 121.0 kg. The molar mass of oxygen is 32kg/kmol and the molar mass of nitrogen is 28 kg/kmol. Assuming that the gases behave ideally, answer the following questions: a) What is the mass of the empty tank? b) What is the composition of the final mixture on a mole basis? c) What is the final pressure of the tank? d) The critical temperature and pressure of oxygen are 154.6K and 49.8atm. Based on these properties, comment on the appropriateness of using the ideal gas law in part a)

Carbon dioxide (CO2) contained in a piston-cylinder arrangement, initially at 5 bar and 400 K, undergoes an expansion to a final temperature of 250 K, during which the pressure-volume relationship is pV1.25 = constant. Assuming the ideal gas model for the CO2, determine the final pressure, in bar, and the work and heat transfer, each in kJ/kg

A Schedule Builder Check #t A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 48.0 cm wide and 57.6 cm high. The maximum safe pressure inside the vessel has been measured to be 6.90 MPa. 3 For a certain reaction the vessel may contain up to 7.89 kg of boron trifluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to 3 significant digits.
