Show hintHide hint
Think about the number of molecules involved.
Question 2.
What is the Lindemann–Hinshelwood mechanism?
Show hintHide hint
Consider how pressure changes could affect reaction dynamics.
3Question 3.
What describes the Lindemann–Hinshelwood mechanism?
- A single step process
- Involves an energized state
- Only applies at high pressures
Show hintHide hint
Think about how reactions shift between states.
4Question 4.
True or False: Unimolecular reactions can show first-order kinetics at high pressures.
- True
- False
Show hintHide hint
Consider the changes in state that occur with pressure.
Question 5.
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.

Which plot gives you a straight line at varying concentrations?
Question 6.
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.
