Alkenes

Question 1

What does a catalytic converter produce?

Answer 1

H2O, CO2, N2

Question 2

What structure does a catalytic converter have and why?

Answer 2

honeycomb, increases SA

Question 3

What is a catalytic converter coated in?

Answer 3

platinum catalyst

Question 4

Flue gas desulphurisation

Answer 4

CaO + SO2 -> CaSO3

Question 5

How is NO/NO2 formed?

Answer 5

Nitrogen in air reacts with oxygen in air at very high high temperatures when fuels are burned

Question 6

What problems do NO, NO2 and SO2 cause?

Answer 6

acid rain

Question 7

What type of alkanes have a higher boiling point, why?

Answer 7

straight chain because the SA contact increases and there’s stronger VDW between molecules

Question 8

What does thermal cracking produce?

Answer 8

alkenes and straight chained alkanes

Question 9

What does catalytic cracking produce?

Answer 9

Motor fuels and aromatic hydrocarbons and cycloalkanes

Question 10

What conditions does catalytic cracking need?

Answer 10

high temp, moderate pressure, zeolite catalyst

Question 11

What conditions does thermal cracking need?

Answer 11

high temp, high pressure
