- Soil acidification due to use of phosphorus fertilizers is small compared to that attributed to nitrogen, due to the lower amounts of this nutrient used and the lower acidification per kg phosphorus. Phosphoric acid is the most acidifying phosphorus fertilizer. - Potassium fertilizers have little or no effect on soil pH.
The factors that change the reaction rates of chemical reactions are: 1)temperature 2)concentration 3)pressure 4)physical state 5)a catalyst.
The Î´G of a Reaction Depends on Changes in Enthalpy (Bond Energy) and Entropy. At any constant temperature and pressure, two factors determine the Î´G of a reaction and thus whether the reaction will tend to occur: the change in bond energy between reactants and products and the change in the randomness of the system.
