Respect to the catalytic cracking process, which converts some heavier fractions of petroleum into lighter fractions, such as gasoline, some statements were made. Which of the following statements is correct?
I. Cracking is economically important because it converts heavier fractions of petroleum into higher-value compounds.
II. Cracking releases a large amount of energy from the breaking of chemical bonds in high-molecular-weight compounds.
III. The presence of a catalyst allows the chemical transformations involved in cracking to occur more quickly.
A) I only.
B) II only.
C) I and III only.
D) II and III only.

A alternativa correta é a letra C) I e III apenas. Explicação: I. Correta. O craqueamento catalítico é importante economicamente porque converte frações mais pesadas do petróleo em compostos de maior valor, como a gasolina. II. Incorreta. O craqueamento catalítico não libera uma grande quantidade de energia da quebra de ligações químicas em compostos de alto peso molecular. III. Correta. A presença de um catalisador permite que as transformações químicas envolvidas no craqueamento ocorram mais rapidamente.
