Question

The following reaction is feasible or not feasible and why?

\[\ce{Br2 + 2NaCl -> 2NaBr + Cl2}\]

Answer 1

1. Feasibility depends on the standard electrode potentials (E°) of the involved half reactions.
2. Bromine (Br₂) has a higher reduction potential (+1.09 V) compared to chlorine (Cl₂).
3. Since (Br₂) is less easily reduced than (Cl₂), it cannot oxidise chloride ions to chlorine gas.
4. The calculated cell potential for the given reaction is negative, indicating the reaction will not occur spontaneously.

Hence, the reaction is not feasible under standard conditions.
