Incorrect in multiple respects. The molar mass of N is 14.006747 g/mol, while ammonia is 17.03052 g/mol. Gas expands to fill the container, so it's only worth discussing in mass terms.
It's rate of production over the area of the catalyst. Put another way, that's 1.5 ± 0.2 mmol/m²s or 25.5 ± 3.4 mg/m²s.
24 hours of production over a catalyst with an area of 1000 m² would create 25 ± 3.4 t. That's about the product weight of a typical full cold / cool towed trailer tank sent to large-scale customers. A commercial ammonia refinery would need many multiples of this area to be economically viable.
