Ethene will not typically react with hydrogen gas through simple bimolecular collisions. Using the picture, explain how this rea
ction 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.
A 0.010 M solution of hydrochloric acid, HCl, has a molarity of 0.010 M. This means that [H+] = 1 x 10-2 M. The pH of this aqueous solution of H+ ions is pH = 2
