Question 1

What is a rate expression?

  • An equation relating reactants' concentration to rate.
  • The same as the balanced chemical equation.
  • A formula only applicable to solid reactants.

💡 Hint: Remember the context of rate and concentration.

Question 2

True or False: The rate constant is dependent on the temperature of the reaction.

  • True
  • False

💡 Hint: Think about factors affecting reaction speed.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a reaction where the rate is found to be dependent on two reactants, A and B. If the reaction is zero order with respect to A and first order with respect to B, how does doubling [B] affect the rate?

💡 Hint: Focus on the definition of reaction order.

Question 2

A student measures the rate at different temperatures and finds that at 300 K, k = 1.00 × 10^-3 s^-1, and at 310 K, k = 3.00 × 10^-3 s^-1. Determine the activation energy using the Arrhenius equation.

💡 Hint: Think about how to isolate Ea using the given temperatures and rate constants.
