8. A catalyst is used in a fuel cell to do what? a. Lower the activation energy of the reaction by adsorping hydrogen gas and splitting it into ions. b. Speed up the reaction to get more energy out. C. Slow down the reaction to make it safer. d. Increase the activation energy to be able to extract more energy from the hydrogen.

Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
