Higher enthalpy
WebThe enthalpy of vaporization(symbol ∆Hvap), also known as the (latent) heat of vaporizationor heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressureat which that transformation takes place. Web23 de abr. de 2024 · As a result, we used the combined methods G4 and G4 (MP2). The thermochemical properties were calculated quantum chemically for high-enthalpy ethynyl hydrocarbons with a Gaussian 09 software and a G4 as the main method to calculate the enthalpy of the formation of molecules.
