Challenge Problems
Push your limits with challenges.
Question 1
A reaction has an activation energy of 100 kJ/mol. Using a catalyst, this energy is lowered to 70 kJ/mol. Calculate the factor by which the reaction rate might increase, assuming transition states are reached more often with the lower activation energy.
💡 Hint: Consider how often molecules hit the transition state.
