Question 1.
What does the Arrhenius equation describe?
Show hintHide hint
Think about how temperature affects chemical reactions.
Question 2.
Define activation energy.
Show hintHide hint
It's like a hill that reactants must overcome.
3Question 3.
What does the Arrhenius equation relate to?
- A. Temperature and rate constant
- B. Pressure and volume
- C. Concentration and reactants
Show hintHide hint
Focus on what determines reaction rates.
4Question 4.
True or False: The activation energy is the energy required for a reaction to occur.
- True
- False
Show hintHide hint
Recall what drives reactions.
Question 5.
A reaction has an activation energy of 50 kJ/mol. Calculate how the rate constant k changes when the temperature is raised from 300 K to 350 K. Use R = 8.314 J/(mol·K).

Remember to plug in the numbers carefully and apply proper conversions!
Question 6.
Discuss how an increase in temperature could affect the safety and efficiency of a reaction in industrial processes.
Show hintHide hint
Think about both sides: benefits from faster reactions and risks involved.
