← ScienceWhich outcome occurs when continuously increasing the temperature of industrial ammonia synthesis catalytic reactor?
A)Reduced catalyst surface area by sintering✓
B)Increased ammonia production limited by equilibrium
C)Decreased nitrogen adsorption by kinetic poisoning
D)Elevated methane production due to methanation
💡 Explanation
When reactor temperature rises, sintering, a process where catalyst particles fuse due to increased atom mobility, occurs because thermal energy overcomes binding forces, reducing overall surface area. Therefore reduced catalyst activity results, as surface for reaction are lost, rather than increased production/methane, which require favorable equilibrium/feed.
