Consider the following reactions that occur during the production of gasoline from a thermal cracking process of kerosene: Reaction 1: C14H30 (l) → C14H30 (g)

Reaction 2: C14H30 (g) → C8H12(g) + C6H14(g) + 2H2(g)

Reaction 3: C8H12(g) → C8H12(l)

Reaction 4: C6H14(g) → C6H14(l)

Which, if any, of the following statements is correct regarding the set of reactions above?

Question 4 options:

The production of C8H12(l) and C6H14(l) from C14H30 (l) involves only chemical changes.

The production of C8H12(l) and C6H14(l) from C14H30 (l) involves only physical changes.

The production of C8H12(l) and C6H14(l) from C14H30 (l) involves both chemical and physical changes.

None of the above statements are correct.
