Which mechanism accelerates the production of ammonia in Haber-Bosch when ruthenium is used?

A)Catalytic surface dissociation
B)Increased kinetic energy transfer
C)Higher reactant partial pressures
D)Lower activation energy barrier

💡 Explanation

Ruthenium catalyzes ammonia synthesis through catalytic surface dissociation by breaking N₂ bonds; because the metal lowers the transition state energy, therefore the dissociation rate increases, producing more NH₃, rather than affecting kinetic energy or pressure.
