Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider an experiment where two solutions of hydrochloric acid at different concentrations react with zinc. Propose a method to measure the reaction rate and predict which concentration will react faster.

💡 Hint: Consider the collision theory while forming your hypothesis.

Challenge 2 Hard

Explain why increasing concentration beyond a certain point may not further increase the reaction rate in the context of simultaneous reactions.

💡 Hint: Think about efficiency and maximum yield.
