The stability of metal oxides at a given temperature is determined by comparing the of reduction for each metal oxide. A metal oxide with a more negative
of reduction is:
More stable
Less stable
Equally stable
Unpredictable
A metal oxide with a more negative of reduction is more stable as it indicates that the reduction of the metal oxide to metal is thermodynamically favoured.
