3 concentration of N 2, H 2, or NH 3.Say we monitor N 2, and obtain a rate of - d[N 2] dt = x mol dm-3 s-1. Since for every mole of N 2 that reacts, we lose three moles of H 2, if we had monitored H 2 instead of N 2 we would have obtained a rate - d[H 2] dt = 3x mol dm-3 s-1.Similarly, monitoring the concentration of NH 3 would yield a rate of 2x mol dm-3 s-1.Clearly, the same …

CH 204: Chemical Reaction Engineering - lecture notes

Introduction 3 If all the reactants and products, and catalysts, if any, are in a single phase, the reaction is said to be homogeneous. An example is provided by the thermal cracking of ethane to ethylene (Froment and Bischo , 1990, p. 29) C2H6(g) C2H4(g)+H2(g) (1.3) On the other hand, if more than one phase is involved, the reaction is said to

3 • For compounds, the molecular mass (in amu) is numerically the same as the mass of one mole of the compound in grams. • Skill 3-1 Calculate the molecular mass of a compound as the sum of the atomic masses of its elements. • Molecular mass H 2 O = (2 x atomic mass of H) + atomic mass of O = 2(1.008 amu) + 16.00 amu = 18.02 amu

For example, the titration of a triprotic acid (an acid with 3 H+) with sodium hydroxide can be written: H 3X(aq) + 3KOH(aq) ⎯→ 3H 2O(l) + K 3X(aq) (X : the unknown anion of the acid) The formula weight of this unknown acid can be calculated by using dimensional analysis. First, the base’s concentration is used to convert the base’s ...
