This is part of a lab report so not sure if the template agrees with what I am asking but basically using the Arrhenius equation in the form of [itex]ln(k)=ln(A)+(\frac{-E_a}{R})(\frac{1}{T})[/itex] I plotted a straight line graph of ln(k) vs 1/T and found the gradient to be -5525.
Its the units that are confusing me so not sure if it is as straight forward as what I have done below.
[tex]
gradient=\frac{-E_a}{R} \\
(gradient)(R)=-E_a \\
(-5525)(8.3145)=-E_a \\
-45937.6=-Ea \\
∴ E_a=45937.6 Joules
[/tex]
any help is really appreciated, thanks.
