Standard gibbs reaction energy

  1. Mar 23, 2008 #1
    1. The problem statement, all variables and given/known data
    Write the half-reactions and the overall reaction for the oxidation of water by F2. Determine the standard potential and DeltaGr(0).

    2. Relevant equations
    I can manage the half-reaction and the overall reaction should be:
    2 H2O + 2 F2 = 4 HF + O2

    3. The attempt at a solution
    OK the Standard potential should be 2,87(F2/F-) - 1,23 = 1,64 V (why is it 2,87-1,64 not opposite?)
    And the answer for gibbs is: -(4mol)*(96,485 kC/mol)(1,64 V)=-633kJ
    I know that the standard gibbs reaction is sum of products molar energy - reactants, but how is it calculated above? and maybe there are other ways to calculate standard gibbs energy, would appreciate if anyone mentions them.
