Solid white
phosphorus has a conventional standard Gibbs energy of zero at 25°C. The
melting point is 44.2°C and ?H°fusion=2510J/mol P4. The
vapor pressure of white phosphorus has the values:
t/°C 76.6 128.0 197.3
p/Torr 1 10 100
a)
Calculate ?H°vapor
of liquid phosphorus
b)
Calculate boiling point of the
liquid
c)
Calculate the vapor pressure at
the melting point
d)
Assuming that solid, liquid and
gaseous phosphorus are in equilibrium at the melting point, calculate the vapor
pressure of solid white phosphorus at 25°C.
e)
Calculate the standard Gibbs
energy of gaseous phosphorus at 25°C.
