Question 1

Why are transition metals commonly used as catalysts?

Answer 1

Existence of partially filled d orbitals with unpaired electrons.
Ability to change oxidation state easily

Question 1

Two main categories of catalyst

Answer 1

Homogeneous and heterogeneous

Question 2

Heterogeneous

Answer 2

Catalyst is in different state to reactants

Question 3

Homogeneous

Answer 3

Catalyst is in same state as reactants. Can be explained in terms of changing oxidation states and formation of intermediate compounds
