The vapor pressure of octane is obtained by the following data- Vp(mmHg) 10 40 100 400 t (°C) 19.2 45.1 65.7 104.0 The graph between ln(vp) and 1/T is to be plotted. The heat of vaporization of octane is to be estimated by this graph. Concept introduction: The relation between pressure, temperature and change in enthalpy of vaporization is as follows: lnP = A − Δ H v a p R ( 1 T ) Here, P = pressure T = temperature Δ H v a p = heat of vaporization = slope A = y-intercept from the graph.
