1
Q
Thermal cracking conditions (2) + main product
A
- 1000 degrees
- 70 atm
- Products are mainly alkenes, for polymers (plastic).
2
Q
Catalytic cracking conditions (3) + main product
A
- 450 degrees
- Slight pressure.
- Zeolite catalyst used (lowers temp+pressure)
- Products are mainly aromatic hydrocarbons.
3
Q
Complete combustion equation
A
Hydrocarbon + oxygen –> carbon dioxide + water
4
Q
Incomplete combustion products
A
- Carbon monoxide (CO)
- Soot (C)
5
Q
Wet scrubbing process
A
Calcium carbonate/oxide used to remove sulphur dioxide from flue gases (alkali neutralisation).
6
Q
Outline free radical substitution
A
initiation (UV light breaks bond), propagation (radical + non-radical), termination (2 radicals react).
7
Q
Catalytic converter reaction
A
2NO + 2CO = N2 + 2CO2
8
Q
Boiling point trend of alkanes
A
Longer chain = more VdW forces
9
Q
How are oxides of nitrogen produced?
A
High temperatures in the car engine cause nitrogen and oxygen to react.
10
Q
Why is sulphur dioxide removed? (2)
A
- Prevents acid rain
- Causes breathing problems
