Nickel,platinum,and Palladium Are Used as Catalysts for Reactions for Hydrogen

Multiple Choice

Nickel,platinum,and palladium are used as catalysts for reactions for hydrogen.These metals have

A) great catalytic activity and not much of surface area, so hydrogen absorbed on the surface of these metals is less reactive than ordinary hydrogen gas.
B) great catalytic activity and lots of surface area, so hydrogen absorbed on the surface of these metals is more reactive than ordinary hydrogen gas.
C) little catalytic activity and lots of surface area, so hydrogen absorbed on the surface of these metals is more reactive than ordinary hydrogen gas.
D) great catalytic activity and lots of surface area, so hydrogen absorbed on the surface of these metals is less reactive than ordinary hydrogen gas.
