हिन्दीAt temperature \( T \), the electron gain enthalpy (\( \Delta_{eg}H^\ominus \)) is related to the electron affinity (\( A \)) by which of the following expressions?
Correct answer · Option 3
\( \Delta_{eg}H^\ominus = -A - \frac{5}{2}RT \)
Explanation
For electron gain, \( \Delta_r C_p^\ominus = -\frac{5}{2}R \), hence \( \Delta_{eg}H^\ominus = -A - \frac{5}{2}RT \).
