The equation used to represents the electron gain enthalpy is
- A \(X(g)+e^{-} \longrightarrow X^{-}(g)\)
- B \(X(s)+e^{-} \longrightarrow X^{-}(g)\)
- C \(X(g) \longrightarrow X^{+}(g)+e^{-}\)
- D \(X(s) \longrightarrow X^{+}(g)+e^{-}\)
Answer & Solution
Correct Answer
(A) \(X(g)+e^{-} \longrightarrow X^{-}(g)\)
Step-by-step Solution
Detailed explanation
When an electron is added to a gaseous atom in its ground state to convert it into a negative ion, the enthalpy change accompanying the process is called electron gain enthalpy \(\left(\Delta e_g H\right)\). It is a direct measure of the ease with which an atom attracts an…
