TED-ED: How to speed up chemical reactions (and get a date) - Aaron Sams

The video uses a story about Harriet and Harold's collision to explain chemical reaction rates. It draws parallels between getting a date for a dance and increasing reaction rates, emphasizing the importance of collision orientation and energy. Five methods to speed up reactions are proposed, using school environment analogies. The role of a catalyst is likened to a matchmaker, reducing activation energy for reactions.

Explain the analogy between reducing hallway size and lowering the volume of a reaction vessel.

What role does a matchmaker play in the context of chemical reactions, according to the text?
