Which change increases reaction rate using a solid catalyst?

A)Increasing catalyst surface area exposed✓

B)Decreasing the reactants' partial pressures

C)Reducing temperature reaction kinetics

D)Shielding catalyst active sites

💡 Explanation

Increasing catalyst surface area will raise the reaction rate, because this increases available active sites on the catalyst via increased surface adsorption. Therefore, reactants contact the catalytic surface more frequently rather than reacting slower at reduced catalyst surfaces.
