Improve Reaction Speed :Temperature and Catalysts

The video tutorial discusses the decomposition of dinitrogen pentoxide and how temperature affects the reaction rate. It explains that higher temperatures increase the number of molecules with energy greater than the activation energy, thus speeding up the reaction. The role of catalysts, such as manganese dioxide, in lowering activation energy and increasing reaction rates is also covered. Additionally, the tutorial highlights how the surface area of reactants, like powdered zinc, influences the rate of reaction by increasing collision frequency.

How does the activation energy change in the presence of a catalyst, and what is its effect on the rate of reaction?

Discuss the relationship between surface area and the rate of reaction using powdered zinc and hydrochloric acid as an example.
