) Choose the correct integrated rate law for each reaction order.
(Enter only the letter to the left of the correct response.)
Reaction Order Answer
zero d
first c
second a

a. l/[A]t = kt + l/[A]0
b. log[A]t = kt +log[A]0
c. ln[A]t = ľkt + ln[A]0
d. [A]t = ľkt + [A]0
e. [A]t = kt + [A]0

---------------------------------
problem 2

Choose the correct half-life for each reaction order.
(Enter only the letter to the left of the correct response.)
Reaction Order Answer
zero E
first D
second A

a. t1/2 = 1 / k[A]0
b. t1/2 = [A]0 / 2k
c. t1/2 = 2 / k[A]0
d. t1/2 = ln 2/ k
e. t1/2 = [A]0 / k
