In the vicinity of the triple point the saturated vapour pressure p of carbon dioxide depends on temperature T as log p = a = 1 – b/T, where a and b are constants. If p is expressed in atmospheres, then for the sublimation process a = 9.05 and b = 1.80 kK, and for the vaporization process a = 6.78 and b = 1.31 kK. Find:
(a) Temperature and pressure at the triple point;
(b) The values of the specific latent heats of sublimation, vaporization, and melting in the vicinity of the triple point.
