Question 1
How does an increase in temperature affect the spontaneity of reactions that have a positive change in entropy?
π‘ Hint: Consider the relationship between temperature and entropy in the Gibbs equation.
Question 2
A reaction has ΞH = -60 kJ and ΞS = -200 J/K. Calculate the temperature at which this reaction would be spontaneous.
π‘ Hint: What happens to spontaneity when ΞH and ΞS are both negative?
