The Clapeyron equation is commonly used to correlate vapour pressure (Pw) with absolute temperature (7), where AH, is the latent heat of vapourization. ΔΗ + B lo g(P.) =- RT A other common vapour pressure correlation is the Antoine equation, which utilizes three parameters A, B, and C, with typically in mm Hg and Tin °C. B log(P,) = A+ T +C A particular chemical is to be liquefied and stored in gas cylinders in an outside storage shed. The following data were obtained in the laboratory bomb calorimeter measurements. In this calorimeter, the liquid was slowly heated in a sealed container while temperature and pressure were recorded as shown below. T(OC) 17 18 19 21 25 27 28 P(mm Hg) 13.6 22.21 35.54 85.98 413.23 832.62 1160.23 (a) Use matlab regression to determine the heat of vapourization and the constant B from the Clapeyron equation. (b) Assuming the yearly low and hot temperatures in the storage shed are-12°C and 49°C, use matlab to calculate the expected vapour pressures at these extreme pressures. () How do your answers (b) change when you use the Antoine corrdation? (d) W hat do you think about storing the cylinders outside?
