What is the free energy change (ΔG) of a spontaneous process?
💡 Hint: Think about the sign of ΔG in spontaneous processes.
True or False: A reaction can be spontaneous even if it is endothermic.
💡 Hint: Consider the relationship between ΔH and ΔS for spontaneity.

Challenge Problems
Push your limits with advanced challenges
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.
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.
