Predict value of change of Hf

  1. Sep 22, 2009 #1
    1. The problem statement, all variables and given/known data

    Predict the value for change in Hf for:
    Br2(g):change in Hf = Br(g) greater than Br(l) ....... (-)

    Br2(l):change in Hf= Br(l) less than Br(g).......(+)

    I2(g): change in Hf= I2(g) greater than I (s)....(-)

    I2(s) : change in Hf= I2(s) less than I(l)...(+)



    2. Relevant equations



    3. The attempt at a solution

    Would I be right on my prediction by using negative or negative signs since it said to predict the value of change on Hf so solid to liquid to gas process.
