Chromium is a transition metal. A student stated that “All catalysts are either transitionmetals or transition metal compounds”. Using your knowledge of chemistry, comment on the truth of the above statement and onhow substances act as catalysts

How would you go about answering this open ended question?

Thats nasty! I would maybe talk about some catalysts in the synthesis topic that aren't transition metals/transition metal compounds. Remember you can get acid and base catalysts. Then I would talk about the features of transition metals/transition metal compounds that make them good catalysts (and do the same for acids and bases). You could maybe draw a diagram showing what happens with a heterogeneous catalyst (adsorption etc.).
