हिन्दीAt temperature \( T \), the relation between the ionization enthalpy (\( \Delta_i H^\ominus \)) and ionization energy (\( E_0 \)) for an atom in gaseous state is:
Correct answer · Option 4
\( \Delta_i H^\ominus = E_0 + \frac{5}{2}RT \)
Explanation
From \( \Delta_i H^\ominus(T) = \Delta_i H^\ominus(0) + \int_0^T \Delta_r C_p^\ominus dT \), since \( \Delta_r C_p^\ominus = +\frac{5}{2}R \), \( \Delta_i H^\ominus = E_0 + \frac{5}{2}RT \).
