Shоwn belоw аre five pоtentiаl energy versus distаnce graphs for a gas, labeled A-E. Please answer the following questions: Part A) 10 points One of these graphs represents a gas model that is described by the following equation: p x (V-nb) = n R T Select which graph (use the letter labels) and explain your choice. Part B) 15 points Shown below is a table about the behavior of some gases. Table 1: van der Waals constants for some gases Substance molar mass, g a (L2-atm mole–2) b (L mol–1) hydrogen H2 2 0.244 0.0266 helium He 4 0.034 0.0237 methane CH4 16 2.25 0.0428 water H2O 18 5.46 0.0305 nitrogen N2 28 1.39 0.0391 carbon dioxide CO2 44 3.59 0.0427 carbon tetrachloride CCl4 154 20.4 0.1383 Using the equation from Part A, calculate the pressure of 25 L of 2 mols of CO2 gas at 298 K and compare it to the pressures you obtain with using the ideal gas and the van der Waals equations. Part C) 10 points Describe and offer a possible explanation for the differences you obtain in the pressures in Part B. Part D) 15 points Assume that the graphs A-E are for H2 gas. Sketch what you might expect the graphs to look like for CO2 gas in comparison to H2 gas (so 2 lines per graph, labeled “H2” and “CO2”, each).   Please do not fill in anything in the box provided below but instead upload your written answer as per instructions.
