MCQ

What is the entropy change (in $J\,{K^{ - 1}}\,mo{l^{ - 1}}$) when one mole of ice is converted into water at ${0\,^o}C$ (The enthalpy change for the conversion of ice to liquid water is $6.0\,\, kJ$ $mo{l^{ - 1}}$ at ${0\,^o}C$)

✓
$21.98$
B
$20.13$
C
$2.013$
D
$2.198$

Answer

Correct option: A.

$21.98$

(a) $\Delta S = \frac{{{q_{rev}}}}{T} = \frac{{6000}}{{273}} = 21.98\,J\,{K^{ - 1}}\,mo{l^{ - 1}}$
