thermodynamically stable vs unstable compound

Postby Peter Dis1G » Wed Feb 07, 2018 10:07 am

Do we have to be able to distinguish and identify those kinds of compounds?

You should be able to distinguish whether a compound is thermodynamically stable (or unstable) by looking at its ΔG° of formation: if ΔG is positive, then its formation is not spontaneous; likewise, the reverse reaction is spontaneous, and it will decompose into its reactants.

For a thermodynamically stable compound, it should be stable if its ΔG° of formation is negative.
