Understanding Chemical Reactions: Collision Theory and Catalysts

The video tutorial explains how collision theory and activation energy are crucial for chemical reactions. It discusses how increasing concentration, pressure, surface area, and temperature can enhance reaction rates. The role of catalysts, including enzymes, in speeding up reactions by lowering activation energy is also covered, with examples like iron in ammonia production and catalase in decomposing hydrogen peroxide.

What is the activation energy in a chemical reaction?

How does increasing the concentration of reactants affect the rate of a chemical reaction?

Explain how increasing the surface area of solid reactants influences reaction rates.

What are the effects of increasing the temperature of reactants on chemical reactions?

Describe the role of catalysts in chemical reactions.
