Antoine's equation is a correlation for vapor pressures based on the Clausius- Clapeyron equation. It has been used over limited temperature ranges. 2. B T + C-273.15 where T is in K and Pvap is in bar. Use Page A55 of Poling et al. for the coefficients needed for ethylbenzene. a equation. log10 Pvap = A Calculate the vapor pressure of ethylbenzene at 347.25 K and 460 K with Antoine's b For the above, experimental values are 0.13332 bar at 347.25 K (Chaiyavech and van Winkle 1959) and 3.325 bar at 460 K (Ambrose et al. 1967), respectively. For each temperature, report the relative deviation using the following equation: Pcalc - Pexp Pexp -× 100[%]
