## Chemistry (4th Edition)

(a) $$Q_c = \frac{[N_2O_4]}{[NO]^2[O_2]}$$ (b) $$Q_c = \frac{[SF_6]}{[F_2]^3}$$ (c) $$Q_c = \frac{[Co(NH_3)_6)^{+3}]}{[Co^{3+}][NH_3]^6}$$ (d) $$Q_c = \frac{[HCOO^-][H^+]}{[HCOOH]}$$
$$Q_c = \frac{[Products]}{[Reactants]}$$ - The balance coefficient of each compound wil be the exponent of its concentration for this equation. - Pure solids and liquids do not appear on this expression.
