Problem

Which of the following is a reaction mechanism for A + B → C that shows the presence of a catalyst?

A.) D + 2 B → E (slow)

A + E → D + C + B (fast)

 

B.) A → D + B (slow)

D + 2 B → C (fast)

 

C.) A → D + E (slow)

D + E + B → C (fast)

 

D.) 2 B → D (fast)

D + A → C + B (slow)

 

E.) 2 B → 2 D + E (slow)

A + 2 D + E → C + B (fast)
