14.3 Reaction Mechanisms, Catalysts, and Reaction Coordinate Diagrams
H2 + Pt ➔ H2-Pt
H2-Pt + C2H4 ➔ C2H6 + Pt
Identify the intermediate and the catalyst.
O3 ⇌ O2 + O (rapid equilibrium) or (fast)
O + O3 ⇌ 2O2 (slow)
What is the intermediate?
What is the rate law?
-Speeds up a reaction (in both directions)
-Lowers the activation energy (in both directions)
-Provides an alternate mechanism (pathway) for the reaction to occur
-Is NOT consumed in the reaction
-Does NOT shift the equilibrium in either direction
