Topic 18: Organic Chemistry

As the molar mass of a compound increases, the entropy:

A. decreases
B. is constant
C. increases

Sagot :

Final answer:

Entropy increases as molar mass of a compound increases due to transformations to less-ordered phases.


Explanation:

Entropy increases as the molar mass of a compound increases. This is evident as substances transform from ordered phases to less-ordered phases, demonstrating a rise in entropy.

For example, the transformation from a solid to a liquid to a gas results in an increase in entropy due to the higher disorder in the gas phase compared to the solid phase.

Similarly, the conversion from fewer molecules to more molecules, especially in gaseous states, contributes to an increase in entropy.
