Question
In the Harber- Bosch process which element is used as
catalyst for ammonia production?Solution
In the Haber process, “ the atmospheric nitrogen (N2) is converted to ammonia (NH3) by reacting it with hydrogen (H2)”.  Here a metal catalyst is used and high temperatures and pressures are maintained. Normally an iron catalyst is used in the process
