It primarily studies the composition of chemical compounds.

It deals with the study of energy changes in chemical reactions. (correct)

Energy is lost during chemical reactions.

Energy cannot be created or destroyed, only transformed from one form to another. (correct)

A measure of the speed of a chemical reaction.

A measure of the energy content of a substance.

A measure of the concentration of reactants in a system.

A measure of disorder or randomness in a system. (correct)

The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another.

Entropy, in the context of chemical thermodynamics, is a measure of the disorder or randomness of a system, often denoted by the symbol 'S'.

The first law of thermodynamics is a fundamental principle in chemical thermodynamics, governing the relationships between heat, work, and energy.
Entropy is a state function, meaning that only the change in entropy (ΔS) is significant, not the absolute value of entropy.
