Challenge Problems

Push your limits with challenges.

Question 1

If you start with a concentration of chlorine at 0.10 M and methane at 0.20 M, calculate the expected rate using the rate law: Rate ≈ k · [Cl₂] · [CH₄] if k = 3.

💡 Hint: Apply the rate law with given concentrations.

Question 2

Discuss how varying the concentrations of reactants might affect the overall rate of a radical chain reaction.

💡 Hint: Reflect on collision theory and reaction rates.
