Challenge Problems
Push your limits with advanced challenges
Consider a reaction with a rate law Rate = k[A]^2[B]. If the concentration of A is tripled and B is held constant, how does the reaction rate change?
💡 Hint: Think about the square relationship in the rate law.
If in a gas-phase reaction the partial pressure of A is increased from 1 atm to 4 atm while B remains constant, what is the expected change in reaction rate?
💡 Hint: Consider how pressure mimics concentration in a gas.
