Abstract
A Calvet microcalorimeter has been utilized to determine the sublimation enthalpy of benzoic acid and anthracene. The vapor pressures measured by Knudsen effusion weight‐loss method over the temperature ranges 338–383°K and 353–432°K were, respectively, , for benzoic acid, and , for anthracene. The Gibbs energy functions for C6H5COOH and C14H10 gaseous molecules have been estimated.
