Nitrogen and oxygen gases are held in a 1.00 m container at 300K. Partial pressures are PN-80 kPa and Por 21 kPa. Collision diameters are dx2= 3.74 and do: -3.57 A. Calculate the average number of collisions per unit volume and per unit time by one molecule of oxygen and one molecule of nitrogen at 300K. The mean speed of gas molecules at 300K is 625 m/s. (Hint: for the N term multiply Nsa by Noz)
