Use of catalyst is a must in the ammonia manufacture, because the reaction is reversible as well as the heat of dissociation of N2 & H2 is high. The presence of promoter along with the catalyst helps in ______________ of the catalyst ?
Correct answer: C. All A, B & C
- A. Stabilisation
- B. Increasing the effectiveness
- C. All A, B & C
- D. Improving the strength & heat resistance
Explanation
Promoters improve several catalyst properties, including activity, stability, mechanical strength and resistance to heat. Therefore, stabilization, effectiveness and strength or heat resistance are all included.
