30. The reaction 2A + 5B → products is second order in A and fourth order in B. What is the rate law for this reaction? (A) rate = k[A]2[B]5 (B) rate = k[A]4[B]2 (C) rate = k[A]2[B]4 (D) rate = k[A]5[B]2 (E) rate = k[A]2/7[B]5/7

35. The complex ions of Zn2+ are all colorless. The most likely explanation for this is: (A) Zn2+ is paramagnetic. (B) Zn2+ exhibits “d orbital” splittings in its complexes such that they absorb all wavelengths in the visible region. (C) Since Zn2+ is a d10 ion, it does not absorb visible light even though the “d orbital” splittings are correct for absorbing visible wavelengths. (D) Zn2+ is not a transition metal ion. (E) None of these is correct.

30. The reaction 2A + 5B → products is second order in A and fourth order in B. What is the rate law for this reaction?
(A) rate = k[A]²[B]⁵
(B) rate = k[A]⁴[B]²
(C) rate = k[A]²[B]⁴
(D) rate = k[A]⁵[B]²
(E) rate = k[A]^2/7[B]^5/7
