← ScienceWhich outcome results when exceeding the transesterification reaction rate limit during biodiesel production?
A)Increased viscosity and reduced atomization✓
B)Improved cold flow and ester purity
C)Lower byproduct formation and simpler filtration
D)Enhanced glycerol removal and reduced sedimentation
💡 Explanation
Exceeding the rate limits causes incomplete reactions because insufficient reactant contact via **mass transport limitation** reduces conversion; therefore viscosity increases from unreacted triglycerides and atomization falters, rather than improving flow since the process never reaches completion.
