Haber's process:
- This process is used in large scale preparations of ammonia.
N2 + 3H2 → 2NH3
- During the process, nitrogen and hydrogen are used in the ratio 1:3.
- The process is exothermic ΔH = -ve in nature means heat is produced in the process.
- According to the Le-chateliar principle, the temperature is kept high to speed up the process.
- The gaseous ammonia produced is converted to liquid ammonia to remove the products formed.
- This drives the reaction forward.
Equilibrium Constants:
- The constants Kp and Kc are both equilibrium constants.
- Kp is used when the concentration terms are given in partial pressures i.e, in gaseous reactions.
- Kc is used when the reaction terms are expressed in molarities.
- The relation between Kp and Kc is given by:
Calculation:
- The relation between Kp and Kc is
For the reaction
N2(g) + 3H2(g)
Hence,
Hence, or the reaction N2(g) + 3H2(g)
