What is coupling of reaction ? How is it useful in metallurgy ? |
|
Answer» Solution :(i) If VALUE of `Delta G` is POSITIVE for any reaction, them to make such reaction spontaneous, it is COUPLED with another reaction of large negative `Delta G` value, so that the SUM of two `Delta G` become negative. This is known as coupling of reaction. (ii) In the metallurgy, thermodynamically INFEASIBLE reaction is coupled with a reaction which has more negative `Delta G`, so that net `Delta G` becomes negative. |
