Question 1
What is the correct expression for the rate of reaction in a second-order reaction involving reactants A and B?
- Rate = k[A][B]
- Rate = k[A]^2
- Rate = k[A][B]^2
💡 Hint: Consider how the concentration influences the rate based on the order.
Question 2
True or False: The order of a reaction must equal the stoichiometric coefficients of the balanced equation.
- True
- False
💡 Hint: Think about empirical observations.

Challenge Problems
Push your limits with challenges.
Question 1
You conduct an experiment with a reaction whose rate law is Rate = k[A]^2[B]. If [A] is tripled and [B] is doubled, calculate the factor by which the rate increases.
💡 Hint: Break down the problem into parts to analyze the effect of each reactant.
Question 2
Analyze the reaction 3A + 2B → products, which has a rate law of Rate = k[A]^2[B]. If experimental data show that halving [A] decreases the rate to one-fourth, explain how this aligns with the order of the reaction.
💡 Hint: Use the concept of order to analyze how changing concentrations relates to rate.
