← ScienceWhich outcome accelerates methanol synthesis in a reactor?
A)Increased catalyst surface area✓
B)Decreased reactor volume
C)Lower activation energy barrier
D)Reduced total system pressure
💡 Explanation
Reaction rate increases due to adsorption by the catalyst surface; this mechanism enhances reactant concentration. The enhanced reactant concentration increases contact because it lowers boundary diffusion and thereby increasing collisions. Therefore, more methanol is synthesized, rather than pressure changes altering equilibrium.
