Secrets of Product Fraction with Activation Energy

The video tutorial explains the concept of activation energy and its role in chemical reactions. It begins by converting activation energy from kilojoules to joules and temperature from Celsius to Kelvin. The tutorial then calculates the fraction of molecules that can react at a given temperature using a scientific calculator. It highlights the significance of effective collisions in reactions and demonstrates how reducing activation energy increases the number of molecules that can react. The conclusion emphasizes that lowering activation energy enhances the reaction rate by increasing the fraction of reacting molecules.

What is the activation energy in joules per mole at 20°C?

Explain the significance of expressing temperature in Kelvin when calculating reaction rates.

What does a fraction of 1.20 into 10 to the power of -9 indicate about effective collisions in a chemical reaction?

How does the fraction of effective collisions change when the activation energy is reduced from 50 kilojoules per mole to 25 kilojoules per mole?

Discuss the relationship between activation energy and the number of molecules that can undergo a reaction.
