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.

PART 2: Written Response Questions Write down your written responses for Questions 18-20 with pen and paper (or on a tablet computer with an electronic pen) and keep the exam and RPNow running. Once you are done or once the time limit is up, you have 20 minutes to scan your written responses to Questions 23-25 and upload them as a single PDF file in the following assignment section in the Midterm 1 Module on Canvas. We can only accept PDF documents. Try to limit the size of your files to less than 5 MB and make sure that your answers are complete and legible. PDF files > 5 MB will be automatically compressed before grading, which may negatively affect readability. If you are using a phone or digital camera to take pictures of your written work and don’t use a scanner app, a popular way to convert your files into a single PDF is to import your pictures into a MS Word document (other word processing software should work, too) and export it into a PDF file. In order to receive full points, the first 3 significant figures of your numerical answers must be correct.
