Challenge Problems
Push your limits with challenges.
Question 1
A reaction with initial concentration of A (0.1 M) and B (0.2 M) yields a rate of 0.04 M/s. If doubling the concentration of A results in a rate of 0.08 M/s, determine the reaction order with respect to A.
💡 Hint: Analyze how changes in concentrations correspond to changes in reaction rates.
Question 2
You have a reaction where the measured rate constant at 300 K is 1.0 × 10$^{-4}$ s^{-1} and at 310 K is 2.5 × 10$^{-4}$ s^{-1} using the Arrhenius equation, calculate the activation energy Ea.
💡 Hint: Apply the two-point form correctly and remember to convert the final answer.
