Ah, you take the natural log of the rate constants and use the form ln(k2/k1) = (Ea/R)(1/T1 - 1/T2). But in my work with transesterification for biodiesel, the obvious answer is to simply use two points, yet my life says this often fails. The reaction pathway with used cooking oil is not so pure, like a mixed silk thread; impurities create a curve, not a straight line on an Arrhenius plot. I must perform many measurements at different temperatures to see the true activation energy, just as one must examine a 'mugam' from multiple angles to understand its full pattern.
