Vedclass · Answer

(A) The reaction involves the transfer of an electron from atom $B$ to atom $A$,which can be represented as: $B + A \rightarrow B^{+} + A^{-}$.
For this reaction to be spontaneous,the total energy change $(\Delta H)$ must be negative.
The energy required to remove an electron from $B$ is its Ionization Energy $(I.E._B)$.
The energy released when an electron is added to $A$ is its Electron Affinity $(E.A._A)$.
Thus,the net energy change is $\Delta H = I.E._B - E.A._A$.
For the reaction to be possible,$\Delta H < 0$,which implies $I.E._B < E.A._A$.
Rearranging the terms to match the provided options,we look for the condition where the energy cost of ionization is offset by the energy gain of electron affinity. The correct condition for the feasibility of electron transfer between two species is $(I.E._B - E.A._A) < (I.E._A - E.A._B)$.

If an electron is transferred from $B$ to $A$,then the reaction is possible when:
