Question 1: Which of the following is a factor that affects the rate of reaction?

Answer: Temperature

Question 2: True or False: Increasing the concentration of reactants typically decreases the rate of reaction.

Answer: False

Question 3: True or False: Catalysts are consumed in the reaction they catalyze.

Answer: False

Question 4: Explain how surface area affects the rate of reaction.

Answer: Increasing the surface area increases the rate of reaction because more particles are exposed to react.

Question 5: Define the term 'activation energy'.

Answer: Activation energy is the minimum energy required for a reaction to occur.

Question 6: Fill in the blank: A catalyst _____ the activation energy of a reaction.

Answer: lowers

Question 7: Match the following terms to their definitions:

Question 8: Calculate the rate of reaction using the formula: Rate = Change in concentration / Time. If the concentration changes by 0.5 mol/L over 10 seconds, what is the rate?

Answer: 0.05 mol/L/s

Question 9: Order the steps in a chemical reaction process from start to finish.

Answer: See full answer key

Question 10: Discuss the effect of temperature on the rate of reaction in detail.

Answer: Increasing the temperature generally increases the rate of reaction because it increases the kinetic energy of the particles, leading to more frequent and energetic collisions.
