Question
The concentration for a first-order reaction is given by the equation:
In[A] = -kt + In [A],
Where:
[A] = concentration of reactant A
[A]o = initial concentration of reactant A
k
= rate constant
t = time
In order to solve for the time, t, in two steps you must:
Step One
Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-
hand side of the expression:
(Be sure that the answer field changes from light yellow to dark yellow before releasing your answer.)
+ In[A] =
-kt + In [A]o

Expert Solution
Explanation

ln [A] = -kt + ln [A]o 

Adding -ln[A]o on both sides,

ln[A] - ln[A]o = -kt + ln[A]o - ln[A]o 

1k x lnAoA = t
