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.<\/section>\n
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.<\/section>\n
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.<\/section>\n","protected":false},"excerpt":{"rendered":"
