Question 1

What does the Collision Theory state about reactions?

  • All collisions result in reactions.
  • Reactions occur only during effective collisions.
  • Collisions have no effect on reactions.

💡 Hint: Think about what makes a collision 'effective'.

Question 2

True or False: Higher temperature decreases the reaction rate.

  • True
  • False

💡 Hint: Recall how temperature affects molecular motion.

Challenge Problems

Push your limits with challenges.

Question 1

Given that the collision frequency for a reaction is 3.5 x 10^9 collisions per liter per second, and the activation energy is 50 kJ/mol at a certain temperature, calculate the rate of the reaction if the temperature is raised by 10 K.

💡 Hint: Don't forget to convert the activation energy into J/mol and use the appropriate values for R.

Question 2

Discuss how increasing pressure in a gaseous reaction influences collision frequency and the rate of reaction.

💡 Hint: Think about how the volume change relates to pressure and how this impacts molecular interactions.
