For reactions in parallel viz A → P (desired product) and A → Q (unwanted product), if the order of the desired reaction is higher than that of the undesired reaction, a_________________?
Correct answer: C. Both A. and B.
- A. Batch reactor is preferred over a single CSTR for high yield
- B. Tubular reactor is preferred over a single CSTR for high yield
- C. Both A. and B.
- D. Single CSTR is the most suitable
Explanation
When the desired reaction has the higher order, high reactant concentration improves its rate relative to the undesired reaction. Batch and tubular reactors maintain higher concentrations than a single CSTR, so both can give higher selectivity and yield.
