Use bond enthalpies to estimate ∆Hrxn for the Haber process below in which nitrogen from the air is ‘fixed’ into a usable form. Compare this with ∆Hrxn calculated from ∆Hºf, which is –46.19 kJ per mol of NH3(g). If there is a difference, why is there a difference? Which do you expect to be more accurate and why? N2(g) + 3H2(g) → 2NH3(g)

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
