← ScienceWhich risk increases when a stirred-tank reactor lacks baffles?
A)Reduced reaction completion rate✓
B)Excessive impeller shaft corrosion
C)Product contamination via backflow
D)Uncontrolled exothermic reaction runaway
💡 Explanation
Without baffles, bulk fluid rotation overshadows effective mixing, thus decreasing contact between reactants. This incomplete mixing causes a decline in collision frequency via reduced mass transfer, therefore diminishing the reaction rate rather than causing corrosion, contamination, or runaway which involve separate phenomena.
