Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What does the rate constant 'k' represent in the rate law equation?

💡 Hint: Think about what affects the speed of a reaction.

Question 2

Easy

How is the overall order of a reaction determined from the rate law?

💡 Hint: Look at the powers of the concentrations in the equation.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

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.
