Use the following equation and chart to make a graph and obtain E_{a} in kJ/mol for this data. [My main problem is setting up and solving the equation mostly because I don't know where A is comming from and I don't know what to put.]

ln(k)=(-E_{a}/R)(1/T)+ln(A)

k=rate constant

E_{a}=activation energy

R=gas constant, 8.314 J/(mol K)

T=temperature in Kelvin

A=Arrhenius constant

T(Kelvin) | k1(sec^{-1}) | k2(sec^{-1}) | k average(sec^{-1}) |
