1. The concept of gas collisions can be applied to the study of metrology. Being the highest composition in atmospheric air (78% by volume), N2 has a collision diameter of 0.369 x 10° m. At 298 K and 1 atm, calculate the single collision frequency of N2 at sea level. The collision frequency of N2 decreases at higher altitude. At 11 km from the sea level, the collision frequency is 3.16 x 10° s1. Calculate the pressure of the gas at this altitude (T = – 220 K). Determine the mean free path for N2 at the altitude of 11 km (the altitude similar in Question 1.ii.) i. ii. iii.

Silicon forms a series of compounds analogous to the al-kanes and having the general formula SinH2n+2. The first of these compounds is silane, SiH4, which is used in the electronics industry to produce thin ultrapure silicon films. SiH4(g) is somewhat difficult to work with because it is py-ropboric at room temperature—meaning that it bursts into flame spontaneously when exposed to air. (a) Write an equation for the combustion of SiH4(g). (The reaction is analogous to hydrocarbon combustion, and SiO2 is a solid under standard conditions. Assume the water produced will be a gas.) (b) Use the data from Appendix E to calculate ? for this reaction. (c) Calculate G and show that the reaction is spontaneous at 25°C. (d) Compare G for this reaction to the combustion of methane. (See the previous problem.) Are the reactions in these two exercises enthalpy or entropy driven? Explain.
