WebAt 34.0 °C, the vapor pressure of isooctane is 10.0 kPa, and at 98.8 °C, its vapor pressure is 100.0 kPa. Use this information to estimate the enthalpy of vaporization for isooctane. Solution The enthalpy of vaporization, ΔHvap, can be determined by using the Clausius-Clapeyron equation (Equation 7.2.5 ): ln(P2 P1) = ΔHvap R ( 1 T1 − 1 T2) The handling of this chemical may incur notable safety precautions.
