Assume the molecules have radius r = 2.50 x 10-10 m. What are the following? (a) the mean free path 6.543E-17 X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m (b) mean free time between collisions for an ozone molecule in the container 1.798E-19 X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. S Need Help? Read It Master It

Explanation / Answer

A) mean free path = 1/(d^2*n)

d- diameter of the molecule

n- number of molecules per unit volume

Mfp = 1/(* (5*10^-10)^2*3.2*6.023*10^23/0.56)

= 3.6493e^-6

B)mean free time = mfp/average speed (avg speed = 8RT/M=483.57)

= 3.6493e^-6/483.57

= 7.5466e^-9s
