Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the reaction A + B -> C with initial concentrations of [A] = 1 mol L⁻¹ and [B] = 1 mol L⁻¹ and a rate constant k = 0.1 L mol⁻¹ s⁻¹, what is the initial rate of reaction?

💡 Hint: Use the rate expression carefully.

Challenge 2 Hard

For a reaction with a k value showing strong dependence on temperature, explain why it is crucial to study this behavior in detail.

💡 Hint: Think about how heat influences molecular movement.
