What is Gibbs Free Energy?
Think about the energy's role in spontaneity.
What does a negative ΔG signify?
Remember the conditions for spontaneity.
What is the criterion for a reaction to be spontaneous?
Consider the sign of Gibbs Free Energy.
True or False: A reaction can be endothermic but still be spontaneous.
Reflect on the relationship between enthalpy and entropy.
A reaction has ΔH = 50 kJ and ΔS = 200 J/K. Calculate ΔG at 298 K. Is the reaction spontaneous?
Convert units where necessary and apply the Gibbs equation.
A process has a ΔH = -100 kJ and ΔS = -300 J/K. Determine the temperature at which the reaction is spontaneous.
Set up the inequality for ΔG and solve for T.
