The values of of and (in cal/K-mol) should be — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Diatomic nitrogen strictly aligns with the standard lower theoretical gaseous heat capacity (parameter i, $8.3\text{ cal/K-mol}$). The polyatomic $\text{H}_2\text{O(g)}$ logically possesses a higher heat capacity due to rotational/vibrational modes, mapping it to parameter ii ($11.3\text{ cal/K-mol}$).
