Use the van der Waals equation of state to calculate the pressure P of 2.80 mol of NH3 at 457 K in a 4.90 L vessel. Use this list of van der Waals constants. Use the ideal gas equation to calculate the pressure P under the same conditions. The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed rms speed =M3RT where R=8.314 J/ (mol. K ) and A is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kg⋅m2/s2). What is the rms speed of Cl2 molecules at 473 K ? rms speed: m/s What is the mins speed of He atoms at 473 K ? rms speed: rm/s
