Explanation / Answer

If you use the Arrhenius equation and plot 1/T vs ln(k) you'll get the scope (Ea/R) and the role (lnA)

ln(K) = ln (A) - Ea/R* (1/T)

Fit the line to a linear equation:

y = -4698,7 X + 27,872 where y =lnK and x= 1/T

Ea / R = 4698,7

Ea = 4698,7 * 8,314472 J/K*mol =39067, 2 J/K*mol = 3,9 kJ / K*mol

ln (A) = 27,872 ----> A= exp(27,872) = 1.272 *1012
