Question
The solubility of $NaCl$(s) in water at 298 K is about 6 moles per litre. Suppose you add 1 mole of $NaCl$(s) to a litre of water. For the reaction: $NaCl$(s) + $H_2O$ -> $NaCl$(aq)
Answer: B
💡 Solution & Explanation
Since 1 mole is less than solubility limit (6 moles/L), dissolution is spontaneous, so Δ G < 0. Dissolution of salt increases disorder, so Δ S > 0.
