2. A student wishes to determine the rate law and activation energy of a reaction. They
analyze their data as described in this exercise.
a. In order to determine the reaction order of a reactant, R, they plot their data
according to the equation In rate = m In[R] + In k' and prepare the graph below.
What is the reaction order of R?
In rate vs. In [R]
In rate
-2.5
-1.5
-8
-1
-0.5
-8.2
-8.4
-8.6
-8.8
-9
-9.2
y = 1.964x-5.106
R2 = 0.9937
-9.4
