Challenge Problems
Push your limits with challenges.
Question 1
Explain why a reaction with ΔH > 0 could still be spontaneous by identifying factors affecting Gibbs energy.
💡 Hint: Discuss how temperature can alter the balance.
Question 2
For the reaction 2 H2(g) + O2(g) → 2 H2O(l), given ΔH = -572 kJ and ΔS = -163.2 J/K, calculate ΔG at 298K.
💡 Hint: Remember to convert ΔS to kJ for consistency.
