Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

How does an increase in temperature affect the spontaneity of reactions that have a positive change in entropy?

💡 Hint: Consider the relationship between temperature and entropy in the Gibbs equation.

Challenge 2 Hard

A reaction has ΔH = -60 kJ and ΔS = -200 J/K. Calculate the temperature at which this reaction would be spontaneous.

💡 Hint: What happens to spontaneity when ΔH and ΔS are both negative?
