Question

Why transition metals and their compounds act as catalyst?

Answer 1

EXPLANATION

• Transition metals are any of various metallic elements such as chromium, iron and nickel that have valence electrons in two shells instead of only one.
• Transition metals are good metal catalysts because they easily lend and take electrons from other molecules.
• Transition metals and their compounds function as catalysts either because of their ability to change oxidation state or, in the case of the metals, to adsorb other substances on to their surface and activate them in the process.
• All this is explored in the main catalysis section.
