Catalyst

Question 1

Whats an complex Ion

Answer 1

When a transition metal ion bonds to one or more ligands by a dative bond (coordinated bond)

Question 2

What is a ligand

Answer 2

A molecule or ion that can donate a pair electron to a transition metal ion to form a coordinated bond

Question 3

What is a catalyst

Answer 3

A catalyst speeds up the reaction, as it leaves parts of the reaction unchanged at the end of the reaction. it also lowers the activation energy

Question 4

What is produced by the contact process? what catalyst is used?

Answer 4

Sulphuric acid by using vanadium oxide

Question 5

What is produced by the Haber process? what catalyst is used?

Answer 5

Ammonia-NH3 by using Iron

Question 6

What happens to vanadium oxide during contact process

Answer 6

The vanadium is reduced (to IV) then its oxidised to bring it back to vanadium oxide where it remains unchanged

Question 7

What are the properties of transition metal

Answer 7

they are good as catalyst
They have variable oxidation state
coloured ion 
they can form a complex bond
they speed up the reaction
lowering the activation energy
