Q1. What is the reactor design for achieving maximum conversion when comparing a Plug Flow Reactor (PFR) and a Continuous Stirred Tank Reactor (CSTR) with equal volume?
Ans. 
PFR achieves maximum conversion due to ideal plug flow and no back-mixing.
• PFR has ideal plug flow, ensuring each reactant spends the same amount of time in the reactor.

• CSTR has back-mixing, leading to lower conversion rates compared to PFR.

• PFR is suitable for reactions with fast kinetics, while CSTR is better for reactions with slow kinetics.
