Problem: Consider this reaction data:A -> productsT(K)    k(s-1)325     0.380725     0.868If you were going to graphically determine the activation energy of this reaction, what points would you plot?Determine the rise, run, and slope of the line formed by these pointsWhat is the activation energy of this reaction?

We need to use the linearized Arrhenius Equation:

$\boxed{\mathbf{ln}\mathbf{ }\mathbf{k}\mathbf{=}\mathbf{-}\frac{{\mathbf{E}}_{\mathbf{a}}}{\mathbf{R}}\mathbf{ }\left(\frac{\mathbf{1}}{\mathbf{T}}\right)\mathbf{ }\mathbf{+}\mathbf{ }\mathbf{ln}\mathbf{ }\mathbf{A}}$

where: 

k = rate constant

E_a = activation energy (in J/mol)

R = gas constant (8.314 J/mol • K)

T = temperature (in K)

A = Arrhenius constant or frequency factor
