Hello, I have been doing some experiements designed to find out the difference in activation energy when reacting magnesium ribbon with Hydrochloric acid and magnesium ribbon with ethanoic acid. I worked out that the activation energy for the HCl experiment was 12.6KJ and the ethanoic experiment was 28.4KJ. I just wanted to know if anyone knows any theory behind this. Thanks

Maybe because the bonds in the stronger acids are weaker, and the bonds in the weak acids are stronger. Or it could be to do with the number of H+ ions
