High Pressure equilibrium data



 Hello,
 I am modelling non-ideal
 behaviour for gazes equilibrium at high pressure
 and so I would need some  experimental
 data at high pressure. For example,
 I am searching for  Kp values,
 or equilibrium compositions ...
 particularly for ammonia synthesis.
 (other data on other compounds would be  welcome also)
 I feel that there are few data at high pressure
 for such data... therefore thanks
 in advance !
