The minimum amount of energy required for a particular reactants to convert into products and is called as Activation Energy.

This activation complex is also termed as Transition State because according to Transition State Theory at transition state the existing bonds tend to increase in length and become weaken while, the new forming bonds tend to decrease in length and start becoming stronger.

Hence, the activated complex is in transition between reactants and products.

Acute diabetes results in the formation of acetone in the body. Hence such patients smell of acetone.

The sodium fusion test, or Lassaigne's test, is used in elemental analysis for the qualitative determination of the presence of foreign elements, namely halogens, nitrogen, and sulphur, in an organic compound. It was developed by J. L. Lassaigne.Silver fluoride is soluble in water and does not precipitate and thus this method cannot be used for detection of fluorine.

In the thermite process, the reducing agent is Aluminium.

Lime is sometimes applied to soil in order to increase the acidity of the soil.

Para-amino salicyclic acid (PAS) is used in the treatment of Tuberculosis.
