Given that two reactions have activation energies of 50 kJ/mol and 100 kJ/mol respectively, discuss how this difference affects their rates at room temperature.
💡 Hint: Consider how temperature influences the energy distribution of particles.
If a catalyst lowers the activation energy by 20 kJ/mol, how does this affect the reaction rate? Calculate the rate increase if the original rate is known.
💡 Hint: Think about how lowering the energy barrier impacts the number of particles successfully initiating the reaction.
