The molecular diameter of CO is 3.19 x1 08 cm. At 295 Kelvin and a pressure of 100 mm Hg, the number of molecules colliding is 2.23 x 1027 per cubic centimeter per second, the number of bimolecular collisions is 1.12 x 1027 , and the mean free path of the gas is 686 nm. For a pressure of 200 torr and a temperature of 295 Kelvin, determine (a) the number of molecules colliding per cubic centimeter per second, (b) the number of bimolecular collisions, and (c) the mean free path of the gas. How pronounced is the effect of the pressure on the quantities sought? Show your answer in terms of percent difference.

Question
Transcribed Image Text:The molecular diameter of CÓ is 3.19 x1 08 cm. At 295 Kelvin and a pressure of
100 mm Hg, the number of molecules colliding is 2.23 x 1027 per cubic centimeter
per second, the number of bimolecular collisions is 1.12 x 1027 , and the mean free
path of the gas is 686 nm. For a pressure of 200 torr and a temperature of 295
Kelvin, determine (a) the number of molecules colliding per cubic centimeter per
second, (b) the number of bimolecular collisions, and (c) the mean free path of the
gas. How pronounced is the effect of the pressure on the quantities sought? Show
your answer in terms of percent difference.
