The rate at which equilibrium is established depends on the rate at which collisions occur. Estimate the number of collisions/(m3 s) among all molecules of air at 1.0 atm pressure and 0 C. Assume for convenience that all molecules are identical and that they have a collision diameter of 0.35 nm and a mass of about 30 amu. (1 atm. = 105 N/m2)
