Explanation

- HETP (Height Equivalent to a Theoretical Plate) and HTU (Height of a Transfer Unit) relate to separation efficiency.  

- They are numerically equal when the operating and equilibrium lines are parallel,

- Meaning the driving force for mass transfer is constant.

Explanation

 The Haber-Bosch process combines nitrogen (N₂) and hydrogen (H₂) under high temperatures and pressures in the presence of a catalyst to produce ammonia (NH₃).
