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.

Nickel, platinum, and palladium have great catalytic activity and lots of surface area, so hydrogen absorbed on the surface of these metals is more reactive than ordinary hydrogen gas. This is because the hydrogen molecules adsorb onto the metal surface and are held in close proximity to each other, enabling them to react more easily. This property makes these metals excellent catalysts for hydrogenation reactions.
