In order to understand why this happens, we need to look at the mechanism. So fisher esterfication is when we react a carboxylic acid with an alcohol along with an acid catalyst(such as H2SO4). The mechanism goes like this: 1. The acid protonates.

To form a bromo- compound, the alcohol is heated under reflux with sodium bromide and concentrated phosphoric acid. The concentrated phosphoric acid reacts with the sodium bromide to form hydrogen bromide, and the hydrogen bromide carries out the substitution. H3PO4 + NaBr → HBr + NaH2PO4. HBr + C3H7OH.
