Catalysis Flashcards
1
Q
Why are transition metals commonly used as catalysts?
A
Existence of partially filled d orbitals with unpaired electrons.
Ability to change oxidation state easily
1
Q
Two main categories of catalyst
A
Homogeneous and heterogeneous
2
Q
Heterogeneous
A
Catalyst is in different state to reactants
3
Q
Homogeneous
A
Catalyst is in same state as reactants. Can be explained in terms of changing oxidation states and formation of intermediate compounds
