41. Solution to Chemistry Problem

Product description

• Based on the dependence of the saturated vapor pressure on the temperature and density of a given substance A (ds and df in kg/m3) at the triple point (tp):
• plot a graph of lgP versus 1/T;
• determine the coordinates of the triple point from the graph;
• calculate the average heat of evaporation and sublimation;
• approximately determine the boiling point of the substance at normal pressure;
• determine the heat of fusion of the substance at the triple point temperature;
• calculate dT/dp for the melting process at the triple point temperature;
• calculate the melting point of the substance at a pressure p, Pa;
• calculate the change in entropy, Gibbs and Helmholtz energy, enthalpy and internal energy for the sublimation process of 1 mole of the substance at the triple point;
• determine the number of thermodynamic degrees of freedom at the following values ​​of temperature and pressure:

a) Ttr.t, ptr.t;

b) Tntk, p= 1.013 x 105 Pa;
