    i have a few questions

    - what if the product in an equilibrium is only a solid, and they ask you to determine the expression for kp, would you divide the reactants by 1?

    - When using the lattice enthalpies from the data booklet do you use the theoretical or experimental value ?

    - does hydrogenation only break C=C bonds or can it also break C=O into C-OH seeing as hydrogenation is the addition of hydrogen to break double bonds!?

    - and with the definition for Dynamic equilibria would you describe it as ' The rate of the forward and backward reaction are equal , and the concentration of products and reactants are the SAME OR EQUAL' ?

    Personally think that paper had tricky bits. Did the graph for titration have 2 vertical sections and 2 equivalence points?

    I think biodiesel production produces pronane-1,2,3-triol always in our spec anyway
