Smaller Molecules have a lower boiling point and are less useful as fuels 1 of 7 What does cracking do? Cracking breakes longer chain molecules to smaller alkane and alkene molecules as there is high demand for short chain but low demand for long chain 2 of 7 What are alkenes used for? Alkenes are used for plastics 3 of 7 The process of cracking is [what]? The process of cracking is random 4 of 7 What are the two types of cracking? The two types of cracking are thermal cracking and catalytic cracking. 5 of 7 What are the conditions for thermal cracking? Thermal Cracking- (750oC) High temperature and high pressure 6 of 7 What are the conditions for catalytic cracking? Catalytic Cracking- (500oC) Low Temperature and Low Pressure, Zeolite Catalyst, Used for most cracking processes. 7 of 7
