Which outcome diminishes transesterification yield in biodiesel production?

A)Saponification forming soap byproducts
B)Increased catalyst activity and pH level
C)Lowering reaction temperature excessively
D)Agitation above optimal kinetic energy

💡 Explanation

Saponification depletes reactants via base-catalyzed ester hydrolysis, forming soap because the equilibrium constant favors this side reaction under certain conditions. Therefore, yield decreases rather than increasing due to side reactions overriding the primary process.
