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

Reaction Order Answer

zero ____
first _____
second _____

a. l/[A]t = kt + l[A]0
b. log[A]t = kt +log[A]0
c. ln[A]t = �kt + ln[A]0
d. [A]t = �kt + [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
    whereas your earlier post gave
    [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.)

    Reaction Order Answer
    zero ______
    first _______
    second _______

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

    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
