Question: 1 / 400

Which transition metal is used in the Haber Process?

Copper

Iron

The Haber Process is an essential industrial method for synthesizing ammonia from nitrogen and hydrogen gases. In this reaction, iron is utilized as a catalyst due to its effectiveness in facilitating the reaction at elevated temperatures and pressures.

Iron promotes the combination of nitrogen and hydrogen molecules, significantly speeding up the reaction rate without being consumed in the process. The ability of iron to serve as a catalyst is attributed to its favorable surface properties, which allow it to adsorb reactant gases and reduce the activation energy needed for the reaction to occur.

Other transition metals such as nickel, copper, and platinum have their own catalytic properties and are used in various other industrial processes. However, in the context of the Haber Process specifically, iron is the primary catalyst chosen for its balance of effectiveness, availability, and cost.
