Choose the correct integrated rate law for each reaction order.?
Choose the correct integrated rate law for each reaction order.

zero ____
first _____
second _____

a. l/[A]t = kt + l[A]0
b. log[A]t = kt +log[A]0
c. ln[A]t = ï¿½kt + ln[A]0
d. [A]t = ï¿½kt + [A]0
e. [A]t = kt + [A]0

is it
zero d
first b
second a?

Amy, I'm confused.
My text, for example, gives for the zero order reaction
[A] = [A]o - kt
[A]t = [A]o - kt.
What's with the extra t in the d answer? Is the [A]*t or perhaps [A]t (from the earlier post since this one didn't give the answers without some gibberish.)

zero ______
first _______
second _______

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

im confused as well this is what the questions says except the 0 are supposed to be smaller and to the lower right side of [A]

• chemistry -

Ok, but you didn't answer my question about the "extra" t. Is that a times t or a sub t.

• chemistry -

They're sub t.

• chemistry -

it is d for the first part but not b and a for the second two

• chemistry -

d
c
a

• chemistry -

d
c
a
is correct, just tried it.

• chemistry -

dca is right

• chemistry -

dca is correct

Check your textbooks...they put the equations in boxes right under the subsection headings
