Question 1
Consider a reaction where ΔH° = -100 kJ/mol and ΔS° = 200 J/mol·K. Evaluate ΔG° at 300 K and determine if the reaction will be spontaneous based on K.
💡 Hint: Use the formulas carefully and remember to convert units!
Question 2
A system has ΔG° = 5 kJ/mol at 298 K. What would be the equilibrium constant K? Is the reaction spontaneous?
💡 Hint: Pay attention to signs when calculating K!
