Two mole of an ideal gas is expanded irreversiubly & isothermally at $2 7^{\circ} C$ untill its volume is doubled and 3.3 kJ heat is absorbed from surrounding. (R. ln $2 = 5.76 J / k mol$ )

Determine $Δ S_{surrounding}$ (in $JK^{- 1}$ ).

Answer:

-11.00

Solution:

$Δ S_{sys t e m} Δ S_{s u rro u n d in g} = n R ln \frac{V _{2}}{V _{1}} = 2 \times R \times ln = 11.52 J / K = - \frac{3.3 \times 1000}{300} \Rightarrow - 11 J / K$
