Question

A reversible reaction occurs as follows:
2 A(g) + B(g) ⇌ C(g) + D(g)
Under a certain set of conditions, the rate law for the forward reaction is determined to be Rate = kf[A][B]. Under these conditions, what is the rate law for the reverse reaction?

A.

Rate = kr[C][D]

B.

Rate = kr[C][D] / [A]

✓ Correct
C.

Rate = kr[C][D] / ([A]2[B])

D.

It cannot be determined from the information given.
