Unformatted text preview: 5.2. STOICHIOMETRY 153 one has 4 H atoms in both the reactant and product sides and 2 O atoms in both the reactant and product sides. In this section stoichiometry will be systematized. Consider now a general reaction with N species. This reaction can be represented by N summationdisplay i =1 i i N summationdisplay i =1 i i . (5.11) Here i is the i th chemical species, i is the forward stoichiometric coefficient of the i th reaction, and i is the reverse stoichiometric coefficient of the i th reaction. Both i and i are to be interpreted as pure dimensionless numbers. In Equation (5.10), one has N = 3 species. One might take 1 = H 2 , 2 = O 2 , and 3 = H 2 O . The reaction is written in more general form as (2) 1 + (1) 2 + (0) 3 (0) 1 + (0) 2 + (2) 3 , (5.12) (2) H 2 + (1) O 2 + (0) H 2 O (0) H 2 + (0) O 2 + (2) H 2 O. (5.13) Here, one has 1 = 2 , 1 = 0 , (5.14) 2 = 1...
