Question

For the net reaction: 2AB + 2C → A₂ + 2BC, the following slow first steps have been proposed.

1. 2C + AB → AC + BC
2. 2AB → A₂ + 2B
3. C + AB → BC + A
4. AB → A + B

What rate law is predicted by each of these steps? Choose from the list below and enter the four letters in order, (e.g. ABCD or DEAB etc.)

A. k[A]

B. k[B]

C. k[AB]

D. k[AB][C]

E. k[A]²

F. k[B]²

G. k[AB]²

H. k[AB]²[C]

I. k[AB][C]²

J. k[AB]²[C]²

A. sec^-1

B. mole L^-1 sec^-1

C. mole^-1 L sec^-1

D. mole² L^-2 sec^-1

E. mole^-2 L² sec^-1
