Questions & Answers

Q: Who discovered catalysis, and when?

Elizabeth Fulhame discovered catalysis in the late 18th Century, well before Jöns Jacob Berzelius in 1835.

Q: How do catalysts lower activation energy in chemical reactions?

Catalysts provide a surface for reaction ingredients to stick to, facilitating bond formation at lower temperatures.

Q: What were Elizabeth Fulhame's primary experiments focused on?

Fulhame's experiments aimed to dye cloth with gold by using metal-salt solutions and exploring reduction and oxidation processes.

Q: How did water play a role in catalyzing metal reduction in Fulhame's experiments?

Water bound to positive metal ions and facilitated their reaction with electrons from reducing agents, lowering activation energy.

Summary & Key Takeaways

• Chemical reactions require activation energy, which can be lowered by catalysts.

• Elizabeth Fulhame's experiments in the late 18th Century led to the discovery of catalysis.

• Catalysis plays a crucial role in industrial processes and biological functions.
