The reactants must first cross the mountain
Chemical reactions are not just about which reactants or products are more stable, but also go through a high-energy state in the middle. This height that needs to be crossed is often referred to as activation energy.
Catalyst offers a low-slope route
Catalysts allow the reaction to take another path with a lower activation energy by adsorbing, changing the local structure, or providing new intermediates. It changes the speed, not the final equilibrium position of the reaction.
The surface is the reaction field
In automobile exhaust purification, ammonia synthesis and fuel cells, the surface structure, pore size and active sites of the catalyst will directly determine the efficiency.
The examples make the science much easier to follow.
A very approachable introduction to the topic.
This connects the classroom concept with a real application nicely.
The explanation of the mechanism was especially helpful.
Looking forward to reading more about the engineering challenges.
This gave me a useful starting point for further research.
The structure is clear and the pacing works really well.
