Challenge Problems
Push your limits with challenges.
Question 1
For a reaction governed by the rate law Rate = k[A]^2[B], how would you calculate the rate if [A] = 0.2 M and [B] = 0.5 M, and k = 3.0 M⁻²s⁻¹?
💡 Hint: Don't forget to square the concentration of [A]!
Question 2
Calculate the effect on the reaction speed if the concentration of A doubles in a first-order reaction Rate = k[A]. What happens to the rate?
💡 Hint: Think about how first-order behavior works.
