Methane (CH4) gas flows into a combustion chamber at a rate of 200. L/min at 1.50 atm and ambient temperature. Air is added to the chamber at 1.00 atm and the same temperature, and the gases are ignited. a. To ensure complete combustion of CH4 to CO2(g) and H2O(g), three times as much oxygen as is necessary is reacted. Assuming air is 21 mole percent O2 and 79 mole percent N2, calculate the flow rate of air necessary to deliver the required amount of oxygen. b. Under the conditions in part a, combustion of methane was not complete as a mixture of CO2(g) and CO(g) was produced. It was determined that 95.0% of the carbon in the exhaust gas was present in CO2. The remainder was present as carbon in CO. Calculate the composition of the exhaust gas in terms of mole fraction of CO, CO2, O2, N2, and H2O. Assume CH4 is completely reacted and N2 is unreacted.
5-54 Automobile air bags are inflated by nitrogen gas. When a significant collision occurs, an electronic sensor triggers the decomposition of sodium azide to form nitrogen gas and sodium metal. The nitrogen gas then inflates nylon bags, which protect the driver and front-seat passenger from impact with the dashboard and windshield. What volume of nitrogen gas measured at 1 atm and 27°C is formed by the decomposition of 100. g of sodium azide?
5-39 An 8.00-g sample of a gas occupies 22.4 L at 2.00 atm and 273 K. What is the molar mass of the gas?

Calculate the fractions of molecules in a gas that have a speed in a range Δv at the speed nvmp relative to those in the same range at vmp itself. This calculation can be used to estimate the fraction of very energetic molecules (which is important for reactions). Evaluate the ratio for n = 3 and n = 4.

a tank used for filling helium balloons has a volume of 0.600m3 and conntains 3.00 mole of helium gas at 30.0o C. Assuminng that the helium behaves like an ideal gas, 1. What is the total translational kinetic energy of the molecules of the gas ? 2.

For O2 at 1 atm and 298 K, what fraction of molecules has a speed between 200. and 300. m/sec? What is this fraction if the gas temperature is 500K? For O2 at 1 atm and 298 K, what fraction of molecules has a speed that is greater than vmp? vave? vrms? Use a spread sheet to calculate these values. For the fraction between 200 and 300, calculate two ways, just using the values at 200 and 300 and then by using the values from 200, 201, 202 ….298, 299, 300. Compare these answers. For the fraction of molecules with a speed that is greater than vmp, vave, and vrms use the size of interval that you feel is appropriate. Compare these fractions.
