The thermal decomposition of amino acids could be carried out at different temperatures and at fixed pressure in a reactor. The effect of temperature on products and pathway could be determined by using time as a function. The hydrothermal decomposition of amino acids takes two key paths
1. The delamination of amino acids to produce ammonia and organi acids
2. The decarboxylation to produce amines and carbonic acids.
The thermal decomposition is and effective experiment that could determine the chemical reaction rate and order of reaction, since it's working with time.
PbCl2 would not dissolve because it is insoluble based on the solubility rules for substances that will dissolve in water. This compound would instead form a solid precipitate at the bottom of the container.
