The following item consists of two statements, Statement I and Stateme

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

Both the statements are individually true and Statement II is the correct explanation of Statement I
Both the statements are individually true but Statement II is NOT the correct explanation of Statement I
Statement I is true but Statement II is false
Statement I is false but Statement II is true

Statement I says that catalytic hydrogenation is highest when the catalyst is in powdered form. Statement II says that when a catalyst is in powdered form, its surface area becomes highest. Both statements are individually true, and Statement II correctly explains why Statement I is true.
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.
Heterogeneous catalysis involves the catalyst being in a different phase from the reactants, often a solid catalyst with gaseous or liquid reactants. In such systems, the surface area of the solid catalyst is a crucial factor affecting the reaction kinetics. Increasing the surface area (e.g., by powdering or using porous materials) generally increases the rate of heterogeneous catalytic reactions.
