FREE Expert Solution

We’re asked to determine the best combination of pressure and temperature to run the reaction to maximize NH3 yield


We’re given a diagram showing the effect of temperature and pressure on NH3 yield in the Haber process.  From this diagram, we can see that:


  • Percent yield of NH3 increases as pressure increases
  • Percent yield of NH3 decreases as temperature increases
