Question 1
A reaction has ΔH° = -100 kJ/mol and ΔS° = 250 J/(K·mol). Calculate ΔG° at 400 K.
💡 Hint: Convert ΔH° to J and apply at the given temperature.
Question 2
Given K = 0.025 at 298 K, calculate ΔG°. What does this suggest about the reaction's spontaneity?
💡 Hint: Find the value of ln K and work with the given values to derive ΔG°.
