Enthalpy change of pentanol
WebExample 7.2.3: Estimating Enthalpy of Vaporization. Isooctane (2,2,4-trimethylpentane) has an octane rating of 100. It is used as one of the standards for the octane-rating system for gasoline. At 34.0 °C, the vapor pressure of isooctane is 10.0 kPa, and at 98.8 °C, its vapor pressure is 100.0 kPa. WebCalculating enthalpy change from bond energies. Bond energies are used to find the ΔH r ꝋ of a reaction when this cannot be done experimentally; The formula is: The formula for calculating the standard enthalpy change of reaction using bond energies. As energy is required to break bonds, bond breaking is endothermic ΔH is positive
