    What about the question after this ? About the activation level
    Sorry, which question was that? Was it the one about the effect of the catalyst on the heat energy given out?

    I think sublimation is s to g, but I can't be sure.

    Edit: it is - "Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase."

    I wrote because they have a high kinetic energy, hard to measure
