Question

Using the ideal van der Waals equation and then the ideal gas equation, calculate the pressure of a 3.524-mol sample of N_{2} gas in a 0.8500-L flask at 415°C. Within the limits of the significant figures justified by these parameters, will the ideal gas equation overestimate or underestimate the pressure? If so, by how much? For N_{2}, a = 1.39 $$L^{2}$atm/mol^{2}$$ and b = 0.0391 L/mol.

Accepted Answer

P_{ideal} = 234.1 atm; P_{vdW} = 255.5 atm; The ideal gas equation underestimate the pressure by 0.091.

Answer

P_{ideal} = 141.2 atm; P_{vdW} = 255.5 atm; The ideal gas equation underestimate the pressure by 0.81.

Answer

P_{ideal} = 234.1 atm; P_{vdW} = 144.6 atm; The ideal gas equation overestimate the pressure by 0.38.

Answer

P_{ideal} = 141.2 atm; P_{vdW} = 144.6 atm; The ideal gas equation underestimate the pressure by 0.024.
