Challenge Problems

Push your limits with challenges.

Question 1

A gas A decomposes into products. Describe how you would set up an experiment to test if the reaction exhibits first-order or second-order kinetics. Include what measurements you'd take and how you'd analyze the data.

💡 Hint: Which plot gives you a straight line at varying concentrations?

Question 2

Given a reaction that shows second-order kinetics at low pressure and first-order kinetics at high pressure, propose a practical approach for an industrial process that utilizes this behavior for manufacturing.

💡 Hint: How can you optimize production using the concepts learned?
