Unformatted text preview: one N 2 molecule make? c. Compare this number to problem 2.d 4. Use the MaxwellBolztmann distribution of speeds to estimate the fraction of CO 2 molecules at 300K that have speeds in the range 200250 m/s. Compare it with the fraction of CO 2 molecules at 30K and 3000K that have the same speed range. Show the plots of the distribution of velocities and the areas under consideration for the 3 Temperatures. 5. A solid surface with dimmensions 3mm x 4.5mm is exposed to He gas at 111Pa and 500K. How many collisions do the He atomsmake with the surface in 10s? 6. From Raff , 17.24 7. From Raff 17.28, 8. From Raff 17.32 9. From Raff 17.34...
