The energy evolved is highest for which of the following reactions
A. `F+e^(-)rarrF^(-1)`
B. `Cl+e^(-)rarrCl^(-)`
C. `S+2e^(-)rarrS^(2-)`
D. `O+2e^(-)rarrO^(2-)`
A. `F+e^(-)rarrF^(-1)`
B. `Cl+e^(-)rarrCl^(-)`
C. `S+2e^(-)rarrS^(2-)`
D. `O+2e^(-)rarrO^(2-)`
Correct Answer – B
Due to high electron affinity of Cl the highest energy is evolved.
