Ethene will not typically react with hydrogen gas through simple bimolecular collisions. Using the picture, explain how this reaction becomes possible.

A: A metal surface is catalyzing the reaction by speeding up the kinetic energy of hydrogen gas and, as a result, breaking its bonds so that it can react with ethene.

B: A metal surface is acting as a catalyst and lowers the activation energy of bond breaking of hydrogen gas.

C: Ethene is stabilized by a metal surface and hydrogen gas catalyzes the metal surface so that it can react with ethene.

D: Ethene is catalyzed by a metal surface and, therefore, raises the activation energy of hydrogen gas breaking apart.
