Question 1

What does the activation energy determine?

  • The rate of the reverse reaction
  • The speed at which products form
  • The temperature of the system

💡 Hint: Think about the energy needed for reactants to interact successfully.

Question 2

True or False: A catalyst is consumed in the reaction.

  • True
  • False

💡 Hint: Consider how catalysts are used in reactions.

Challenge Problems

Push your limits with challenges.

Question 1

A chemical reaction had a measured rate constant of k at 298 K. If the temperature is increased to 308 K and the rate constant doubles, what can be inferred about the activation energy?

💡 Hint: Consider how the Arrhenius equation illustrates the relationship between k and T.

Question 2

If a certain catalyst reduces the activation energy from 100 kJ/mol to 60 kJ/mol, how would this impact the reaction rate at a fixed temperature?

💡 Hint: Remember what a catalyst does to activation energy and how it influences molecular collisions.
