Chapter 13

Chapter 13. Chemical Equilibrium. Chemical Equilibrium. Chemical equilibrium occurs in chemical reactions that are reversible. In a reaction such as: CH 4 (g) + H 2 O(g) ? CO(g) + 3H 2 (g) The reaction can proceed in both directions CO(g) + 3H 2 (g) ? CH 4 (g) + H 2 O(g).

Chemical Equilibrium

Chemical Equilibrium. In general the combustion products consist of more than just CO 2 , H 2 O, O 2 , and N 2 For rich mixtures CO also exists in the products and at high temperatures the molecules dissociate to form H, O, OH, NO via the following reactions:.
