20) Vapor pressure In simplification, the relation between the vapor pressure and temperature of a pure substance can be described by the August equation (for the pressure p in bar and the temperature T in Kelvin) as follows: B In(p) = A - 2/1 Hereby, the heat of vaporization is assumed to be independent of the temperature and A and B are experimentally determined constants. a) Describe the term vapor pressure! b) Explain why most solid substances exhibit a very low vapor pressure. In contrast, give an example of a solid with a significantly high vapor pressure. c) Using the August equation, determine the temperature and pressure of the triple point of sulfur dioxide (SO2). For solid SO2, the constants of the August equation are determined to be A = 15.901 and B = 3883 K-¹. For liquid SO2 the parameters are A = 11.401 and B = 2995 K-¹.
