Sa. Derive the formula of us for a van der Waals gas. (3 marks) b. Consider 0.315 mol of Carbon dioxide behaving as a van der Waals gas (a = 3.610 atm L mol; b=0.0429 L mol) at a volume of 2.36 L and pressure of 1.00 atm. What is the value of ur for the carbon dioxide? (3 marks) c. Calculate the change in enthalpy for the gas in part b if it's pressure was increased to 4.00 atm and the temperature doubled. Assume that ur for carbon dioxide is constant over this pressure range. It's Cp = 37.11 JK mol"? (4 marks)
