Question

Which of the following statement is incorrect?

• A. The greater the disorder in an isolated system, the higher is the entropy.
• B. The crystalline solid state of a substance is the state of lowest entropy.
• C. Entropy is not the measure of average chaotic motion of particles in the system.
• D. The gaseous state of a substance is state of highest entropy.
• E. \( \Delta S \) is related to \( q \) and \( T \) for a reversible reaction as \( \Delta S = \frac{q_{{rev}}}{T} \)

Hint:

Entropy is a measure of disorder and is directly related to the randomness of particles in a system. The more chaotic the system, the higher the entropy.

Answer 1

The Correct Option is C

Entropy is indeed the measure of the disorder or randomness of a system, and it is related to the chaotic motion of particles in the system. Statement (C) is incorrect because it misrepresents the definition of entropy. 
Thus, the correct answer is (C).
