4. In the phase diagram of pure ammonia, NH3, the solid-liquid coexistence line can be
expressed as
P = 69.1-T – 13503 solid-liquid coexistence line
|
and the liquid-vapor coexistence line can be expressed as
P = 7.642x10-4.T² – 0.3183-T+ 33.4
liquid-vapor coexistence line
where pressures are given in units of atm and temperatures are in units of K.
The triple point of the ammonia phase diagram has a temperature of
a. Tự = 197.2 K
b. Tự = 195.4K
c. Tự = 410.6 K
d. Tự is indeterminate
