Activation energy is the minimum energy needed for ‘successful collisions’ where atoms within the reactants rearrange to form products. It can be represented on an energy level diagram.

starts at the energy of the reactants is equal to the difference in energy between the top of the 'hump' and the reactants The overall change in energy in a reaction is the difference between the ...

Researchers at Oxford University have developed a new method to extract fluorine from fluorspar (CaF2) using oxalic acid and a fluorophilic Lewis acid in water under mild reaction conditions.
