Which process limits reaction rate when solid catalyst particles agglomerate within slurry reactor?

A)Reduced surface area for reactant adsorption
B)Increased heat transfer away from catalyst
C)Enhanced product diffusion from active sites
D)Decreased pore diffusion within particles

💡 Explanation

When catalyst particles agglomerate, surface area available for reactant adsorption decreases because clumping of particles reduces exposure of active sites. Therefore reduced surface area limits reaction, rather than enhanced heat/mass transfer which are promoted by more dispersed catalysts.
