Solution: Effect of temperature and pressure on NH3 yield in the Haber process.Each mixture was produced by starting with a 3:1 molar mixture of H2 and N2.At what combination of pressure and temperature should

Problem

A diagram shows that the percent of NH3 increases with increasing pressure and decreases with increasing temperature.
Effect of temperature and pressure on NH3 yield in the Haber process.
Each mixture was produced by starting with a 3:1 molar mixture of H2 and N2.

At what combination of pressure and temperature should you run the reaction to maximize NH3 yield?

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
