Choose the substance which has higher possible entropy (per mole) at a given temperature. — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Gases have higher entropy than solids. For a given gas at a constant temperature, entropy increases as pressure decreases (volume increases). Thus, $\text{N}_2$ at the lowest pressure ($0.00001\text{ atm}$) has the highest molar entropy.
