Lead Time. Its lone electron absorbs strongly in the visible range, so it is a deep maroon color. A computer animation representing what occurs at the particulate level was available but it is missing. Vol 79, 7, Putti, A. Curriculum Notes. One day of lead time is required for this project. The demonstration should be performed shortly after the materials are brought into the classroom or the hot water will cool down.

    Four glass tubes are sealed with NO2 gas. The first tube is placed in a hot water bath. The second is placed in ice-water. The third is placed in a flask filled with.
    Since there are twice as many moles of gas on the right hand side of the equation, the entropy change of this reaction is positive, so you would expect the product to be favored at higher temperatures.

    The Science Teacher. At room temperature and normal atmospheric pressure the reactant and product are in a fairly well distributed equilibrium. Student ideas regarding chemical equilibrium.

    A YouTube video of this demonstration is available.
