The equation 4KNO2 -> 2K2O + 4N2 + 2O2.

  1. Detailed information about the equation 4KNO2 -> 2K2O + 4N2 + 2O2 -> :
    This equation describes the thermodynamic decomposition process of potassium nitrite (KNO2) to produce potassium oxide (K2O), dinitrogen (N2), and oxygen (O2).

  2. Reaction conditions:
    This decomposition reaction occurs when KNO2 is heated.

  3. Reaction Process:
    When KNO2 is heated, it decomposes to form K2O, N2, and O2.

  4. Phenomenon occurred:
    When the reaction occurs, the solid KNO2 will disappear and the reaction space will gradually be filled with N2 and O2 gas. K2O will also appear as a new solid substance.
