The Peng–Robinson equation of state is used to compute the correction factor due to gas-phase nonideality, , in the high-pressure synthesis of ammonia (), known as the Haber process. In addition, the extent of reaction is computed. This Demonstration plots these two quantities versus pressure for temperatures ranging from 580 K to 710 K.


Here, the method of arc-length continuation is applied to solve the ammonia synthesis problem.
