The catalyst used to convert sodium to sodium amide is
$\mathrm{V}_{2} \mathrm{O}_{5}$
$\mathrm{Pt}$
$\mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3}$
$\mathrm{Fe}$
Solution
Sodium amide can be prepared by the reaction of sodium with ammonia gas, but it is usually prepared by the reaction in liquid ammonia using iron(III) nitrate as a catalyst. The reaction is fastest at the boiling point of the ammonia.
