Challenge Problems
Push your limits with challenges.
Question 1
For the reaction 2H₂(g) + O₂(g) ⇌ 2H₂O(g), it was found that at 298 K, ΔG° = -237.1 kJ. Calculate Kp for this reaction at this temperature.
💡 Hint: Ensure unit conversion consistency and use properties of logarithms.
Question 2
Discuss how an increase in temperature would alter the value of K for the reaction N₂(g) + 3H₂(g) ⇌ 2NH₃(g) (ΔH° = -92.4 kJ).
💡 Hint: Think about how temperature affects heat in chemical reactions.
