List of top Chemistry Questions on Spontaneity asked in KEAM

The entropy of vaporization of a liquid is $58 \, JK^{-1} \,mol^{-1}$. If $100\, g$ of its vapour condenses at its boiling point of $123^{\circ}C$, the value of entropy change for the process is (Molar mass of the liquid = $58 \,g \,mol^{-1})$

Choose the reaction with negative $\Delta$S value
