Phosphoric acid acts as a negative catalyst.
Negative catalysts (inhibitors) are those substances (or factors) which slow down the chemical reactions by decreasing the required activation energy for the reaction, for example the decomposition of Hydrogen peroxide may be slow down by adding a small amount of phosphoric acid in it.
