cracking is a form of what?
A
thermal decomposition
3
Q
why is cracking a form of thermal decomposition?
A
the molecules are broken down into simpler molecules by heating them
4
Q
why are loner molecules produced from fractional distillation cracked into smaller ones?
A
because there’s more demand for products like petrol than for diesel
5
