Statement I: The solubility of any gas in any liquid is an exothermic process.<br><br>Statement II: — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Dissolution of gas in liquid is always accompanied by decrease in entropy (ΔS < 0). For the process to be spontaneous (ΔG < 0), it must be exothermic (ΔH < 0). Thus, Statement I is correct. However, not all gases are highly soluble in all liquids (e.g., $N_2$ has very low solubility in water). Thus, Statement II is incorrect.
