Unformatted text preview: ture of all four gases. A reaction in which the reactants are not completely consumed to form products because the reverse reaction also occurs (products form reactants) is a re ve rs ible re action. Such reactions are indicated by the use of double arrows as shown in equation 3: (3) 4 NH3(g) + 3 O2(g) 2 N2(g) + 6 H2O(g) In dealing with equilibrium reactions, several definitions are useful and are given below. www.webassig n.net/ebooks/wsug encheml1/lab_9/manual.html 1/5 4/15/13 Lab 9 - Eq uilibr ium and Le Châtelier ' s Pr inciple Products are the chemical species to the right of the equilibrium arrow, as the reaction equation is written. Re actants are the chemical species to the left of the equilibrium arrow, as the reaction equation is written. The forward re action is the process as written from left to right in the reaction equation. The re ve rs e re action is the process as written from right to left in the reaction equation. In mixtures of the sort shown in equation 3 4 NH3(g) + 3 O2(g) 2 N2(g) + 6 H2O(g) , products are constantly being transformed to reac...
