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.)
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 ______
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
P. 570 10th ed chang onwards
