Abstract

Assessed values are presented for the thermodynamic properties of Te(2)(g) and of selected gaseous monotellurides, viz. those of the elements Ag, Al, As, Au, B, Bi, Cu, Ge, Mn, O, P, Pb, S, Sb, Se, Si and Sn. The thermal functions of the molecules are computed at a reference pressure of 1 atm (0.101325 MPa) with conventional statistical-mechanical relations and experimentally determined molecular constants, supplemented by estimated data where necessary. The standard enthalpies of formation and the dissociation energies are calculated from partial pressures or equilibrium constants reported in the literature for equilibria involving the molecule of interest or on spectroscopic results where available. For each monotelluride, a table lists the molecular parameters used in the calculation of the thermal functions as well as equilibrium constants at 298.15 K and at 100 K intervals between 0 and 3000 K for the reaction MTe(g) = M(g) + Te(g).
