The van-der-Waals parameters for carbon dioxide gas are: a = 3.640 bar L2/mol2 b = 4.267 x 10-2 L/mol A 2.30 Liter cylinder contains 235 g of carbon dioxide at a temperature of 240.0°C. Part a) Calculate the pressure of the gas using the ideal gas equation of state. Provide your answer in bar. Part b) Calculate the pressure of the gas using the van-der-Waals equation of state. Provide your answer in bar. Part c) Modify the van-der-Waals equation to include only repulsive interactions between the gas molecules and calculate the resulting prediction for the pressure. Provide your answer in bar. Part d) Calculate the pressure needed to compress the gas to half of its initial volume at a constant temperature using the (full) van-der-Waals equation of state. Provide your answer in bar. Solve this problem on paper, document your approach and provide intermediate results. Report the final answers with 3 significant figures. Scan the pages(s) and upload them for grading.
