Advanced Higher Chemistry - Unit Two - Free Energy
The second law of thermodynamics states that for a reaction to be feasible the total entropy of a reaction system must increase. Does this mean the total entropy change will be positive or negative?
Heat energy released by the reaction system into the surroundings ________ the entropy of the surroundings?
Heat energy absorbed by the reaction from the surroundings ______ the entropy of the surroundings?
What equations are used to calculate the change in free energy (Gibb's free energy)?
ΔG˚ = ΔH˚ - TΔS˚
Under non-standard conditions any reaction is feasible is ΔG is positive or negative?
When does ΔG = 0?
