### Examples of Change Values = 0

Can someone give some important to remember examples of the following?

When:
a) Delta S=0
b) Delta G=0
c) Delta U=0

a). when change in entropy is zero, it is a reversible reaction or reaction at equilibrium
b). when change in gibbs free energy is zero, the reaction is at equilibrium and doesn't favor the products or reactants
c). when change in internal energy is zero, the reaction is isothermal (I think there may be more cases of this but I am not sure)
