Stability

How do you know what values make a reaction thermodynamic-ally and kinetically stable and unstable?

You need to look at the values of ∆G_rxn to determine whether the reactants(∆G_rxn>0) or products(∆G_rxn<0) are more thermodynamically stable. To determine kinetically stability, we need to look at how large or small ΔG‡ is. If ΔG‡ is small, it is kinetically unstable. If ΔG‡ is large, it is more kinetically stable therefore it is kinetically controlled.

Thermodynamically stable means that delta G is negative. So when delta G <0 the products are thermodynamically stable. If Delta G>0 the reactants are thermodynamically more stable.
