Question

Why are chemists interested in studying thermochemistry: a) heat is often absorbed during chemical reaction b) heat is often absorbed during chemical reaction, but never released c) heat is often released during chemical reaction d) heat is often released during chemical reaction, but never absorbed

Answer 1

The correct answer is (C).

Chemists are more interested in studying the amount of heat produced in a reaction that gets released eventually.

For example, the combustion of organic substances in our body such as sugar, fat (takes place within cells ) produces heat energy that helps in physical activities.

Thermochemistry deals with both absorption and release of heat energy in any chemical reaction.
