Product description
5. For pure benzene, the temperature dependences of saturated vapor pressure are known at equilibrium liquid-vapor and crystals-vapor
Vapor crystals T,c 236.5 244.0 256.4 261.7 279.8
R,Pa 133 284 854 1133 5330
Liquid-steam Т,к 279.8 288.6 303.0 315.4 333.8
R,Pa 5330 7999 16317 26660 53320
Necessary:
1) Build on MILLIMETER PAPER (Fig. 1) the temperature dependences of the saturated vapor pressure over a liquid substance and over a solid substance (crystals)
2) Construct on MILLIMETER PAPER (Fig. 2) the dependences of the natural logarithm of saturated vapor pressure on the reciprocal temperature for the equilibria under consideration.
3) Determine the coordinates of the triple point.
4) calculate graphically the molar heats of evaporation and sublimation, assuming that they do not depend on temperature.
5) Determine the molar enthalpy, entropy and Gibbs energy of melting at the triple point.
