5 Questions
What does the change in Gibbs free energy (∆G) determine?
Whether a given chemical change is thermodynamically possible or not
What does the change in enthalpy (∆H) measure?
The heat content of a system at constant pressure
What does a negative ∆G indicate about the reactants and products?
The reactants have more free energy than the products
What does a positive change in enthalpy indicate about a reaction?
The reaction was endothermic (absorbed heat)
What does entropy measure in a system?
The system's thermal energy per unit temperature that is unavailable for doing useful work
