71. Given the following reactions and the corresponding rate laws, in which of the reactions might the elementary reaction and the overall reaction be the same? (a) Cl2 CO ⟶ Cl2CO rate = k ⎡ ⎣Cl2 ⎤ ⎦ 3/2 [CO] (b) PCl3 Cl2 ⟶ PCl5 rate = k ⎡ ⎣PCl3 ⎤ ⎦ ⎡ ⎣Cl2 ⎤ ⎦ (c) 2NO H2 ⟶ N2 H2 O rate = k[NO] ⎡ ⎣H2 ⎤ ⎦ (d) 2NO O2 ⟶ 2NO2 rate = k[NO]2 ⎡ ⎣O2 ⎤ ⎦ (e) NO O3 ⟶ NO2 O2 rate = k[NO] ⎡ ⎣O3 ⎤
