3. Substance A evaporates at temperature T. Calculate the specific heat of evaporation at the same temperature. Write an equation for the dependence of the heat of vaporization of substance A on temperature. Take the heat capacities of saturated vapor and liquid from the reference book, assuming that they are constant in a given temperature range. Heat, evaporation at normal boiling point are given in the table.
Option 11
Substance A - TiCl4
Tn.t.n, K 409
∆H test at Тн.т.н., KJ/mol 35.75
T,K 309 406
