 i have been scouring the internet trying to find a literature value for the activation energy of the reaction between oxalic acid and potassium permanganate but have found nothing!!

[Aldebaran]

At high school level,  problems relating to activation energy are often calculated from given rates of reaction determined by experiment at different temperatures and the activation energy is then calculated using the Arrhenius equation. Is this the case you are being presented with? If so you might find  a way to solve your problems by looking into the Arrhenius equation.

i have to conduct the experiment and then get the activation energy from my results, but then i have to compare what i get with other studies online to get literature values and determine percent error

And one hint Mn2+ is a catalyst. The reaction runs autocatalytic.

More Mn2+ is produced the decomposition of Permanganate and oxalic acid will be accelarated.
