Calculate the enthalpy of reaction for the following:

N2 + 3H2 -> 2NH3 they are all gases.

Is this reaction endothermic or exothermic?

  • chemistry -

    Look up delta Hf values in your text or notes, then calculate
    deltaHrxn = (n*DHproducts)-(DHreactants).
    The sign is - for exothermic; + for endothermic.

    Thanks!

  • chemistry--typo -

    I omitted an n in that. It should be
    deltaHrxn = (n*DHfproducts) - (n*DHfreactants)
