Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A researcher is studying a reaction with reactants A and B using the initial-rate method. If doubling [A] causes a rate increase of 8 times, while doubling [B] results in a rate increase of 4 times, what are the orders of reaction with respect to A and B?

💡 Hint: Think about how each reactant's concentration affects the rate.

Challenge 2 Hard

In a series of reactions studied using spectrophotometry, the absorbance of a product was measured over time. If after 10 seconds, the absorbance was 0.5 and after 20 seconds it was 1.0, calculate the rate of production assuming a linear increase. What does this imply about the reaction order?

💡 Hint: Consider how absorbance relates to concentration changes and the rate type.
