Expert Solution

Solution.

The plot of lnk = f(1/T) is given below:

The Arrhenius equation in the linearized form is

Comparing this equation to the line fit equation from the plot, we can conclude that

To find other activation parameters, we will use the equations:

The activation entropy can be calculated using the equation
