Catalysis occurs on the surface of the catalyst. A larger surface area provides more active sites for the reaction to take place, thus increasing the reaction rate. Powdering a solid increases its total surface area significantly.
The following item consists of two statements, Statement I and Statement II. Examine these two statements carefully and select the correct answer using the code given below : Code : Statement I : Catalytic hydrogenation is highest when the catalyst remains in the powdered form Statement II : When a catalyst is in the powdered form, its surface area becomes highest
