Challenge Problems
Push your limits with challenges.
Question 1
If a reaction has H = -200 kJ and S = 0.5 kJ/K, calculate the temperature at which this reaction becomes non-spontaneous.
💡 Hint: Set up the inequality for G, and solve for T.
Question 2
Consider a biochemical reaction occurring at 310 K with H = -40 kJ and S = 0.1 kJ/K. Evaluate the spontaneity of the reaction.
💡 Hint: Plug in values for H and TS into the Gibbs equation.
