Chapter 13 - Chemical Equilibrium - Exercises - Page 644: 21


a) $K$ $=$ $[NO]^{2}$$/$$[N_{2}][O_{2}]^2$ b) $K$ $=$ $[NO_{2}]^{2}$$/$$[N_{2}O_{4}]$ c) $K$ $=$ $[SiCl_{4}][H_{2}]^{2}$$/$$[SiH_{4}][Cl_{2}]^{2}$ d) $K$ $=$ $[PCl_{3}]^{2}[Br_{2}]^{3}$$/$$[PBr_{3}]^{2}[Cl_{2}]^{3}$

Work Step by Step

note: if aA + bB >>>> cC + dD then equilibrium constant K = $[C]^{c}[D]^{d}$$/$$[A]^{a}[B]^{b}$ concentration of product over concentration of reactants IMPORTANT: solids (s) and Liquids (l) are not included in the equilibrium expression
