Challenge Problems
Push your limits with advanced challenges
Given the concentration of a reactant over 3 time intervals: 0.10 M, 0.08 M, and 0.06 M over the times 0 s, 50 s, and 100 s respectively, calculate the average rate over the first interval.
💡 Hint: Break down the concentration change over the respective time.
An instantaneous rate is observed as 0.002 M/s at 30 seconds for a reaction. If the concentration at 30 seconds was 0.15 M, what would the new concentration be after 10 seconds?
💡 Hint: Use the instantaneous rate to guide concentration changes over a time frame.
