Questiоn 9, pаrt f.Questiоn 9: Reаl gаses, wоrk, heat, and interpretationA 1.50 mol sample of CO2(g) is held at 35.0 degrees C in a 30.0 L container. For CO2, use a = 3.59 atm L^2 mol^-2 and b = 0.0427 L mol^-1. Use R = 0.082057 L atm mol^-1 K^-1 or R = 8.314 J mol^-1 K^-1 as appropriate, and 1 atm = 101325 Pa.Part f. Calculate the pressure using only the van der Waals volume correction, nRT/(V - nb).
Questiоn 11, pаrt e.Questiоn 11: Hess lаw аnd temperature-dependent reactiоn enthalpyEthanol combustion can be written as C2H5OH(l) + 3 O2(g) -> 2 CO2(g) + 3 H2O(l). Use standard formation enthalpies at 298 K: C2H5OH(l) = -277.0 kJ mol^-1, CO2(g) = -393.5 kJ mol^-1, H2O(l) = -285.8 kJ mol^-1, and O2(g) = 0. Use constant molar heat capacities: C2H5OH(l) = 112.4 J mol^-1 K^-1, O2(g) = 29.4 J mol^-1 K^-1, CO2(g) = 37.1 J mol^-1 K^-1, and H2O(l) = 75.3 J mol^-1 K^-1.Part e. Calculate the heat-capacity correction from 298 K to 350 K.
Questiоn 9, pаrt i.Questiоn 9: Reаl gаses, wоrk, heat, and interpretationA 1.50 mol sample of CO2(g) is held at 35.0 degrees C in a 30.0 L container. For CO2, use a = 3.59 atm L^2 mol^-2 and b = 0.0427 L mol^-1. Use R = 0.082057 L atm mol^-1 K^-1 or R = 8.314 J mol^-1 K^-1 as appropriate, and 1 atm = 101325 Pa.Part i. If the gas expands reversibly and isothermally from 30.0 L to 45.0 L, calculate w for the ideal gas.
Questiоn 9, pаrt j.Questiоn 9: Reаl gаses, wоrk, heat, and interpretationA 1.50 mol sample of CO2(g) is held at 35.0 degrees C in a 30.0 L container. For CO2, use a = 3.59 atm L^2 mol^-2 and b = 0.0427 L mol^-1. Use R = 0.082057 L atm mol^-1 K^-1 or R = 8.314 J mol^-1 K^-1 as appropriate, and 1 atm = 101325 Pa.Part j. For the ideal-gas isothermal expansion in part i, determine Delta U and q.
