← ScienceWhich outcome accelerates alkane cracking within catalytic converters?
A)Increased catalyst surface area✓
B)Decreased reactor back pressure
C)Elevated exhaust gas temperature
D)Reduced catalyst pore diameter
💡 Explanation
Increased surface area concentrates reactants on catalytic sites; this lowers the activation energy via surface adsorption. Therefore, reaction rate increases, rather than reactions limited by diffusion or equilibrium concentration given other operating constraints.
