) 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 = –kt + ln[A]0
d. [A]t = –kt + [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
okay its not showing up again. blah.
I read the first post you made and asked a question about the answers but you never answered.
oh yea sorry about that i solved the one that i posted about last
for problem two its not EDA
its BDA...
just did it
The correct integrated rate law for each reaction order is as follows:
Reaction Order:
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 = –kt + ln[A]0
d. [A]t = –kt + [A]0
e. [A]t = kt + [A]0
To determine the correct integrated rate law, you need to know the reaction order. The reaction order can be determined experimentally by analyzing the rate of reaction with respect to each reactant. Once you know the reaction order, you can choose the correct integrated rate law from the given options.
Similarly, for the correct half-life for each reaction order:
Reaction Order:
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
The half-life of a reaction is the time it takes for the concentration of a reactant to decrease by half. The correct half-life for each reaction order depends on the rate constant (k) and the initial concentration of the reactant ([A]0). It is important to know the reaction order to choose the correct half-life equation.
