WBJEE · Chemistry · Thermodynamics (C)
The change of entropy \((d S)\) is defined as
- A \(d S=\frac{\delta q}{T}\)
- B \(d S=\frac{d H}{T}\)
- C \(d S=\frac{\delta q_{eqv}}{T}\)
- D \(d S=\frac{d H-d G}{T}\)
Answer & Solution
Correct Answer
(C) \(d S=\frac{\delta q_{eqv}}{T}\)
Step-by-step Solution
Detailed explanation
The entropy is the measure of disorder or randomness in a system. When a system changes from one state to another, the change of entropy, \(d S\) is given by \[ d S=\frac{\delta q_{\mathrm{rev}}}{T} \]
