5. Consider air (which consists of 79 mol% of N2 and 21 mol% of O2) at 300 K: (a) What is the self-collision rate of nitrogen molecules in number of collisions per m³ per second? (b) What is the self-collision rate of oxygen molecules in number of collisions per m' per second? (c) What is the collision rate between oxygen and nitrogen molecules in number of collisions per m' per second? Hint: Use the hard-sphere model where all the collisions are effective. The diameters of oxygen molecules and nitrogen molecules are 3.61 Å and 3.75 Å, respectively. For self-collision scenarios, calculate reduced mass based on two molecules of the same size and mass and be mindful that the number of collisions is double counted.

Mc ALEKS Graw Type here to search A For many purposes we can treat ammonia (NH3) as an ideal gas at temperatures above its boiling point of -33. °C. Suppose the temperature of a sample of ammonia gas is raised from -24.0 °C to 21.0 °C, and at the same time the pressure is changed. If the initial pressure was 5.6 atm and the volume increased by 30.0%, what is the final pressure? Round your answer to the correct number of significant digits.
