A rapid TGA method is used for which of the following process?

(a) Decomposition of polymers exothermally

(b) Decomposition of enzymes exothermally

(c) Decomposition of crystals endothermally

(d) Decomposition of reactions isothermally

This question was addressed to me in an international level competition.

Origin of the question is Applications of DTA and TGA in portion Thermal Analysis of Solid State Chemistry

The correct choice is (d) Decomposition of reactions isothermally

To explain I would say: An accurate and rapid TGA method is to study the decomposition of reactions isothermally, the TGA furnace is arranged at a pre-set temperature and the sample introduced directly at this temperature. After allowing 2 to 3 minutes for the sample with time can be followed. The process may be repeated at other temperatures and the results analyzed to determine reaction mechanisms, etc.
