N2  - Equilibrium pressures of the reaction 2ZrCl3(c) + ZrCl2(c) + ZrCl4(g) measured by a cooling curve modification of the dew-point technique are fitted over the range 613-723°K, by the relation           Log10pmm = -6246/T ? 11.632 ± 0.05 (S.D.).     Derived thermochemical data are &#916;H298 = 30.1 ± 0.5 kcal and &#916;S298 = 39.1 ± 1 e.u., consistent with estimated &#916;Hf298ZrCl2 = - 136 kcal/mole and &#916;Hf298ZrCl2 = -136 kcal/mole, S298ZrCl3 = 36.4 e.u. and S298ZrCl2 = 28.3 e.u.
