Chapter 17, Problem 85A

Interpretation Introduction

Interpretation:

The merits of a flow out process for chemical reactions that are reversible needs to be explained.

Concept introduction:

Le Chatelier principle states that a system at equilibrium when subjected to changes in the system adjusts it self to attain the equilibrium state again.

Answer to Problem 85A

The flow out process is a better and more economical option than batch process because in batch process the reactants are not completely used as the reaction is reversible. So there is wastage in separating the reactants from the products in every batch which is less efficient as compared to flow out process.

Explanation of Solution

In the flow out process, the reaction mixture will not be able to attain a stable equilibrium point due to the continuous removal of products and addition of reactants. These two processes shift the equilibrium to the right according to Le Chatelier principle and increase the rate of forward reaction making the process more efficient.

Conclusion

Flow out process is better than the batch process for a reversible reaction due to the above stated merits.
