A certain VOC compound has measured vapor pressures equal to 0.1316 psia at 31.65° F, and 0.2034 psia at 44.57° F. Determine the constants A and B in a Classius-Claperon type equation for estimating vapor pressures of this VOC. Use the equation to estimate the vapor pressure of the VOC at 77.0 deg F. Ans. 0.55 psia.
