Source sentences:
text: A catalyst is something that provides an alternative route for a reaction to occur, either by allowing the reaction to occur at a different transition state or by changing the activation energy, and the catalyst itself does not undergo any chemical change during the reaction (materials that do undergo chemical changes are not classified as catalysts, and it gets murkier when you ask about physical changes, i believe there is an iron based material that acts like a catalyst but undergoes a physical change)
text: A catalyst provides an alternative route to products, the catalytic route being subject to lower activation energy than in the uncatalyzed reaction.
