Challenge Problems
Push your limits with advanced challenges
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.
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.
