Catalyst used for ammonia synthesis is
Correct answer: D. Fe
- A. Cu
- B. Co
- C. Zn
- D. Fe
Explanation
Finely divided "Fe" is used as a catalyst in Haber process. Cr2O3+ MgO + SiO2 is used as promoter.N2 +3H2 Fe/MgO/Cf2O3/SiO,⇌450°C/200 atom 2NH3

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
