[PROBLEM SET FROM R. CHANG TEST
BANK]
For the hypothetical reaction A + 3B → 2C, the rate of appearance of C given by (∆[C]/∆t) may also be
5.
expressed as
∆[C]/∆t = ∆[A]/∆t
A.
∆[C]/∆t = -(3/2) ∆[B]/∆t
B.
∆[C]/∆t = -(2/3) ∆[B]/∆t
C.
∆[C]/∆t = -(1/2) ∆[A]/∆t
D.
6.
For the overall chemical reaction shown below, which one of the following statements can be rightly
assumed?
(g) → 2S(s) + 2H
2H
S(g) + O

A.
The reaction is third-order overall.
B.
The reaction is second-order overall.

C.
The rate law is, rate = k[H

E.
The rate law cannot be determined from the information given.
The reaction A + 2B → products has been found to have the rate law, rate = k[A] [B]

For the hypothetical reaction A + 3B → 2C, the rate should be expressed as
8.
rate = ∆[A]/∆t
A.
B.
rate = -∆[C]/∆
C.
rate = -3(∆[B]/∆t)
D.
rate = (1/2)(∆[C]/∆t)
E.
rate = (1/3)(∆[B]/∆t)
The reaction A + 2B → products has the rate law, rate = k[A][B]
