Challenge Problems
Push your limits with challenges.
Question 1
A chemical reaction has ΔH = -120 kJ and ΔS = 0.4 kJ/K. Calculate the temperature at which this reaction becomes non-spontaneous.
💡 Hint: Use the equilibrium temperature formula.
Question 2
Discuss how an increase in temperature might affect a system where ΔH is +30 kJ and ΔS is +0.1 kJ/K. Will it eventually become spontaneous?
💡 Hint: Refer to the influence of temperature on ΔG.
