For a reversible spontaneous change S is - Vidyadip

MCQ

For a reversible spontaneous change $\Delta S$ is

A
$\frac{{\Delta E}}{T}$
B
$\frac{{P\,\Delta V}}{T}$
✓
$\frac{q}{T}$
D
$RT\, log\, K$

✓

Answer

Correct option: C.

$\frac{q}{T}$

c
$ds =\frac{ dq \cdot rev }{ T }$

$\Delta s =\frac{\int dq \cdot rev }{ T }$

$\int dq \cdot$ rev.q (for rev. provess)

$\Delta s =\frac{ q }{ T }$
