← ScienceWhich outcome occurs when platinum gauze catalyzes ammonia oxidation?
A)Increased nitrogen monoxide production✓
B)Decreased reaction vessel temperature
C)Inhibition of catalyst active sites
D)Promotion of runaway side reactions
💡 Explanation
Increased nitrogen monoxide production occurs because platinum's catalytic activity lowers the activation energy. This accelerates ammonia oxidation via the Ostwald process, therefore favoring NO production rather than unwanted nitrogen gas byproducts under regulated temperatures.
