Haber Process Advanced

An ideal simulation for both junior and senior chemistry.


One of our most interactive and dynamic simulations, this program helps simplify the concepts involved in the Haber Process and the production of ammonia. Take control of the production plant and investigate which conditions best suit the production process, with the aim of producing the most product at the cheapest rate.

What are the effects of different catalysts and why one is better than the other?


Examine the molecular interactions of this equilibrium reaction step by step or investigate the economic ramifications of choosing various temperature, pressure, catalyst and gas mixtures.

The Model Screen allows your students to examine the:
  • Cyclic nature of the Haber Process.
  • Equilibrium reaction in ammonia production.
  • Effect of pressure and temperature on equilibrium.
  • Effect of different catalysts on reaction rate.
  • Effect of different catalysts production economics.

In the detailed Reactor Screen students still have full control over the various parameters, however as shown below they can observe the effects of their actions at the molecular level.

Allow the reactions to proceed or step through the various events occurring. The student has full control over temperature, pressure, catalyst, gas concentrations and the units used. They can even isolate the reaction vessel and investigate ammonia equilibrium in a closed system, with and without catalysts.

Extensive graph options allow the students to observe up to 12 different variables at once. Imagine changing the gas concentration and watching the reaction rate graphs move toward equilibrium or the gas concentration graphs alter to fit the new conditions.

As a teacher you have control over exactly which data is automatically collected during experiments. You may choose to eliminate some types to simplify data for your students or to enable them to calculate that data at a later time.

Data can be printed and exported for later use.

A Units Screen enables the user to select the units used for pressure, temperature, concentration, currency and production levels. Energy, maintenance and raw material costs can also be altered to help economically oriented investigations.

Recommended experiments include:
  • Lab 1 - Haber Process Introduction
  • Lab 2 - Concept of Equilibrium
  • Lab 3 - Effect of Catalysts on the Ammonia Equilibrium
  • Lab 4 - Effect of Pressure on Ammonia Production
  • Lab 5 - Effect of Temperature on Ammonia Production
  • Lab 6 - Best Conditions for Ammonia Production - 1
  • Lab 7 - Best Conditions for Ammonia Production - 2
  • Lab 8 - Conditions for Economic Ammonia Production - 3
