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.

In this experiment a student found that when she increased the temperature of a 544 mL sample of air from 22.8°C to 33.6°C, the pressure of the air went from 1012 cm H₂O up to 1049 cm H₂O. Since the air expands linearly with temperature, the equation relating P to t is of the form: b. Find the value of b. (Substitute known values of P and into Equation 9 and solve for b.)

A sample of argon gas at STP occupies 17.0 L. What mass of argon is present in the container?
Effusion is the process where a gas flows through a small hole in a container. Graham’s Law of Effusion says that the rate of effusion of a gas from a particular hole is inversely proportional to the square root of the MW of the gas (at constant temperature and pressure).

In a 0.5 L container of gas at sea-level where the temperature is 298 K, the collision rate between molecules, Z, is 1.2 x 104 s. If the collision cross-section, o, of 9 × 10-19 m² remains unchanged, what is the change in collision rate if the temperature is cooled to 170 K? Note: the relative average speed is assumed to remain unchanged. 17
