Challenge Problems
Push your limits with advanced challenges
A chemical reaction had a measured rate constant of k at 298 K. If the temperature is increased to 308 K and the rate constant doubles, what can be inferred about the activation energy?
💡 Hint: Consider how the Arrhenius equation illustrates the relationship between k and T.
If a certain catalyst reduces the activation energy from 100 kJ/mol to 60 kJ/mol, how would this impact the reaction rate at a fixed temperature?
💡 Hint: Remember what a catalyst does to activation energy and how it influences molecular collisions.
