Understanding Heterogeneous Catalysis in A Level Chemistry

When you hear the term "heterogeneous catalysis,” what comes to mind? If you’re studying for your A Level Chemistry exam, let’s clear up any confusion and dive into the essentials of this fascinating topic. So, here’s the scoop: heterogeneous catalysis refers to a type of chemical reaction where the catalyst—often a solid—is in a different physical state than the reactants, which might be in a gas or liquid form. Pretty straightforward, right? But hang on, there’s more to the story!
