Challenge Problems
Push your limits with challenges.
Question 1
Given the rate law Rate = k [A]^2 [B], if [A] is doubled and [B] remains constant, how will the rate change?
💡 Hint: Consider how the change in concentration of A affects the rate.
Question 2
A zero-order reaction has a rate constant k = 3 mol L‒1 s‒1. If the initial concentration of reactant R is 1 mol L‒1, how long will it take for the concentration to fall to 0.2 mol L‒1?
💡 Hint: Use the zero-order integrated rate equation.
