Other Condition: at high temperature
Explanation: The ideal environmental conditions for a reaction, such as temperature, pressure, catalysts, and solvent. Catalysts are substances that speed up the pace (velocity) of a chemical reaction without being consumed or becoming part of the end product. Catalysts have no effect on equilibrium situations.
Mix the aluminum and potassium oxide mixture in a ceramic cup. Then, heat it up at the right temperature.
At high temperatures, aluminum reduces many metal oxides (behind aluminum in the metal reactivity series) into free metal. This reaction is called the aluminum thermal reaction. Since K is in front of Al in the metal reactivity series, this reaction does not occur.

Pass the ammonia gas through a glass tube containing heated potassium oxide
Beside being a weak base, ammonia also exhibits reducing property. When heated, ammonia can reduce some metal oxides into metals (except the oxides of sodium, potassium, barium, calcium, magnesium)
