Assuming that the latent heat of sublimation of ice \(L_{\mathrm{S}}=2500 \mathrm{~kJ} / \mathrm{kg}\) is independent of temperature and the specific volume of the solid phase is negligible compared to the specific volume of the vapor phase, \(v_{\text {vapor }}=k T / P_{\sigma}(T)\), integrate the Clausius-Clapeyron equation (4.7.7) to obtain the coexistence pressure as a function of temperature. Compare your result to the experimental vapor pressure of ice from \(T=0\) to the triple point. The equilibrium vapor pressure at the triple point is \(612 \mathrm{~Pa}\).
