The following figure shows the energy profile of a nucleophilic substitution reaction. Potential energy :ÖH H HII.C H C-1 H HO--C---I HH Reaction coordinate H -CH HO–CHITH H + 1 According to this, it is correct to affirm: O The activation energy (4G°) shows that it is thermodynamically favorable. O Represents a reaction that occurs in one step where a pentavalent chemical species is formed. O The intermediate has lower energy than any transition state. O The formation of the intermediate releases energy and is therefore thermodynamically favourable.
