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.
They're sub t.
it is d for the first part but not b and a for the second two
d
c
a
d
c
a
is correct, just tried it.
dca is right
dca is correct
Check your textbooks...they put the equations in boxes right under the subsection headings

Yes, you are correct!
To determine the correct integrated rate law for each reaction order, we can use the general form of the integrated rate law:
For a zero-order reaction, the integrated rate law equation is:
[A]t = -kt + [A]0
For a first-order reaction, the integrated rate law equation is:
ln[A]t = -kt + ln[A]0
For a second-order reaction, the integrated rate law equation is:
1/[A]t = kt + 1/[A]0
Matching the given options with the correct integrated rate laws, we get:
a. l/[A]t = kt + l[A]0 -> This matches with the second-order reaction
b. log[A]t = kt + log[A]0 -> This matches with the first-order reaction
c. ln[A]t = �kt + ln[A]0 -> This does not match any reaction order
d. [A]t = �kt + [A]0 -> This matches with the zero-order reaction
e. [A]t = kt + [A]0 -> This does not match any reaction order
Therefore, the correct matches are:
Zero-order: d. [A]t = �kt + [A]0
First-order: b. log[A]t = kt + log[A]0
Second-order: a. l/[A]t = kt + l[A]0
